This is detected by checking if the connection has shard awareness (using the existing _is_not_scylla() method). Changes to both SchemaParserV3 and SchemaParserV4: - Modified _query_all() to conditionally append triggers query only for non-ScyllaDB - Modified _query_all() response unpacking to use array slicing for cleaner code - Modified get_table() in V3 to conditionally query triggers This eliminates unnecessary failed queries to system_schema.triggers on ScyllaDB.

Under resource pressure (--smp 2 --memory 2048M shared across 3 nodes), the SSL handshake plus CQL negotiation can exceed the default 5-second connect_timeout, causing intermittent OperationTimedOut failures. Fix by passing connect_timeout=30 to TestCluster (matching the generous timeout recommended for slow-starting clusters) and increasing the wait_until_not_raised parameters from (0.5, 10) to (1, 30), consistent with other wait_until_not_raised calls in this file (lines 773, 855). --- tests/integration/standard/test_client_routes.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tests/integration/standard/test_client_routes.py b/tests/integration/standard/test_client_routes.py index 9471c95867..5a20421276 100644 --- a/tests/integration/standard/test_client_routes.py +++ b/tests/integration/standard/test_client_routes.py @@ -1059,7 +1059,7 @@ def test_ssl_without_hostname_verification_through_nlb(self): def routes_visible(): with TestCluster( contact_points=["127.0.0.1"], - ssl_context=ssl_ctx, + ssl_context=ssl_ctx, connect_timeout=30, ) as c: session = c.connect() rs = session.execute( @@ -1071,7 +1071,7 @@ def routes_visible(): wait_until_not_raised( lambda: self.assertTrue(routes_visible()), - 0.5, 10, + 1, 30, ) with Cluster( From db317eb3645495232664f99c4a452da67b74903e Mon Sep 17 00:00:00 2001 From: Yaniv Michael Kaul Date: Sun, 29 Mar 2026 16:32:08 +0300 Subject: [PATCH 044/111] tests: register custom 'last' pytest mark to suppress warning The test_tablets.py file uses @pytest.mark.last to ensure the decommission test runs last.

Fix: explicitly grant id-token:write to the test-wheels-build job so the permission cap satisfies the reusable workflow's requirement.

Fix: flip to `>` so the guard fires while the deadline is in the future.

Follow-up to #820. The upload_pypi job in lib-build-and-push.yml was never reachable: none of the four caller workflows pass upload: true. build-push.yml and publish-manually.yml already publish from their own separate jobs (necessary due to how PyPI Trusted Publishing embeds the caller workflow path in the OIDC token). Because the reusable workflow declared 'permissions: id-token: write' for upload_pypi, GitHub's static permission validation forced build-test.yml (a pull_request workflow, which defaults to id-token: none) to also declare id-token: write — granting unnecessary privileges to a job that only builds wheels. Changes: - Rename lib-build-and-push.yml -> lib-build.yml (it only builds now) - Remove upload input and upload_pypi job from the reusable workflow - Remove 'permissions: id-token: write' and 'with: upload: false' from build-test.yml (no longer needed) - Update all callers (build-push.yml, publish-manually.yml, build-pre-release.yml) to reference the new workflow path and drop upload: false from with: blocks - Replace TODO comments in build-push.yml and publish-manually.yml with an explanatory comment: the separate publish job is now intentional design, not a temporary workaround --- .github/workflows/build-pre-release.yml | 2 +- .github/workflows/build-push.yml | 9 +++--- .github/workflows/build-test.yml | 6 +--- .../{lib-build-and-push.yml => lib-build.yml} | 29 ++----------------- .github/workflows/publish-manually.yml | 8 +++-- 5 files changed, 15 insertions(+), 39 deletions(-) rename .github/workflows/{lib-build-and-push.yml => lib-build.yml} (88%) diff --git a/.github/workflows/build-pre-release.yml b/.github/workflows/build-pre-release.yml index e1326b6aa5..f6473c1cc3 100644 --- a/.github/workflows/build-pre-release.yml +++ b/.github/workflows/build-pre-release.yml @@ -15,7 +15,7 @@ on: jobs: build-and-publish: - uses: ./.github/workflows/lib-build-and-push.yml + uses: ./.github/workflows/lib-build.yml with: python-version: ${{ inputs.python-version }} target: ${{ inputs.target }} diff --git a/.github/workflows/build-push.yml b/.github/workflows/build-push.yml index 7414daec3a..3a3d93171a 100644 --- a/.github/workflows/build-push.yml +++ b/.github/workflows/build-push.yml @@ -10,11 +10,12 @@ on: jobs: build-and-publish: name: "Build wheels" - uses: ./.github/workflows/lib-build-and-push.yml - with: - upload: false + uses: ./.github/workflows/lib-build.yml - # TODO: Remove when https://github.com/pypa/gh-action-pypi-publish/issues/166 is fixed and update build-and-publish.with.upload to ${{ endsWith(github.event.ref, 'scylla') }} + # Publishing is a separate job (not inside the reusable workflow) because PyPI Trusted Publishing + # requires the *caller* workflow path in the OIDC token.

The workaround does not work for two reasons: 1. GITHUB_WORKFLOW_REF is a GitHub runner-provided variable used to populate the OIDC token. Setting it in a child process's environment has no effect on the token GitHub's infrastructure mints. 2. The OIDC token is minted when pypa/gh-action-pypi-publish runs (in the publish job), not when cibuildwheel runs (in build-wheels). The variable was set in the wrong job entirely. The actual working workaround is running pypa/gh-action-pypi-publish directly in the caller workflow (build-push.yml, publish-manually.yml), which is already done. This variable override is dead code with no effect. --- .github/workflows/lib-build.yml | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/.github/workflows/lib-build.yml b/.github/workflows/lib-build.yml index f8d0d7a4cc..bc094d1b11 100644 --- a/.github/workflows/lib-build.yml +++ b/.github/workflows/lib-build.yml @@ -140,12 +140,12 @@ jobs: if: matrix.target != 'linux-aarch64' shell: bash run: | - GITHUB_WORKFLOW_REF="scylladb/python-driver/.github/workflows/lib-build.yml@refs/heads/master" cibuildwheel --output-dir wheelhouse + cibuildwheel --output-dir wheelhouse - name: Build wheels for linux aarch64 if: matrix.target == 'linux-aarch64' run: | - GITHUB_WORKFLOW_REF="scylladb/python-driver/.github/workflows/lib-build.yml@refs/heads/master" CIBW_BUILD="cp3*" cibuildwheel --archs aarch64 --output-dir wheelhouse + CIBW_BUILD="cp3*" cibuildwheel --archs aarch64 --output-dir wheelhouse - uses: actions/upload-artifact@v7 with: From 5cd0158e1775e6ce27148fe733a9030ca4d3bfa4 Mon Sep 17 00:00:00 2001 From: "renovate[bot]" <29139614+renovate[bot]@users.noreply.github.com> Date: Tue, 21 Apr 2026 19:38:23 +0000 Subject: [PATCH 055/111] chore(deps): update astral-sh/setup-uv action to v8 --- .github/workflows/docs-pages.yml | 2 +- .github/workflows/docs-pr.yml | 2 +- .github/workflows/integration-tests.yml | 2 +- .github/workflows/lib-build.yml | 4 ++-- 4 files changed, 5 insertions(+), 5 deletions(-) diff --git a/.github/workflows/docs-pages.yml b/.github/workflows/docs-pages.yml index 0da86fef34..9d14b9c4d8 100644 --- a/.github/workflows/docs-pages.yml +++ b/.github/workflows/docs-pages.yml @@ -31,7 +31,7 @@ jobs: fetch-depth: 0 - name: Install uv - uses: astral-sh/setup-uv@v7 + uses: astral-sh/setup-uv@v8.1.0 with: working-directory: docs enable-cache: true diff --git a/.github/workflows/docs-pr.yml b/.github/workflows/docs-pr.yml index 4158c2912e..f0aa64d628 100644 --- a/.github/workflows/docs-pr.yml +++ b/.github/workflows/docs-pr.yml @@ -37,7 +37,7 @@ jobs: fetch-depth: 0 - name: Install uv - uses: astral-sh/setup-uv@v7 + uses: astral-sh/setup-uv@v8.1.0 with: working-directory: docs enable-cache: true diff --git a/.github/workflows/integration-tests.yml b/.github/workflows/integration-tests.yml index 89f62963b0..fde1ab3e1d 100644 --- a/.github/workflows/integration-tests.yml +++ b/.github/workflows/integration-tests.yml @@ -68,7 +68,7 @@ jobs: run: sudo apt-get install libev4 libev-dev - name: Install uv - uses: astral-sh/setup-uv@v7 + uses: astral-sh/setup-uv@v8.1.0 with: python-version: ${{ matrix.python-version }} diff --git a/.github/workflows/lib-build.yml b/.github/workflows/lib-build.yml index bc094d1b11..21dcc0604f 100644 --- a/.github/workflows/lib-build.yml +++ b/.github/workflows/lib-build.yml @@ -96,7 +96,7 @@ jobs: echo "CIBW_BEFORE_TEST_WINDOWS=(exit 0)" >> $GITHUB_ENV; - name: Install uv - uses: astral-sh/setup-uv@v7 + uses: astral-sh/setup-uv@v8.1.0 with: python-version: ${{ inputs.python-version }} @@ -159,7 +159,7 @@ jobs: - uses: actions/checkout@v6 - name: Install uv - uses: astral-sh/setup-uv@v7 + uses: astral-sh/setup-uv@v8.1.0 with: python-version: ${{ inputs.python-version }} From 32548a66010ac1fa3fa722afe3abf39469ff281c Mon Sep 17 00:00:00 2001 From: Yaniv Michael Kaul Date: Tue, 14 Apr 2026 20:03:56 +0300 Subject: [PATCH 056/111] Fix unfilled format string in add_execution_profile timeout message The error message at Cluster.add_execution_profile() had an unfilled %s placeholder: 'Failed to create all new connection pools in the %ss timeout.'

OperationTimedOut now carries optional timeout and in_flight fields that are appended to the exception message when present (e.g. "(timeout=10.0s, in_flight=42)"). All seven production raise sites in connection.py and cluster.py pass these values where available. Additionally, debug-level log lines are emitted for: - Client-side request timeouts (host, timeout, in_flight, orphaned) - Server-side read/write timeouts (host, consistency, received/required, data_retrieved/write_type, retry decision) A helper _retry_decision_name() translates RetryPolicy constants to human-readable strings for the log messages. New keyword-only parameters are backward compatible — existing callers that pass only positional errors/last_host continue to work unchanged.

Changes: - Replace atexit.register(partial(_cleanup, _global_loop)) with a wrapper function _atexit_cleanup() that looks up _global_loop at shutdown time - Remove unused 'partial' import from functools - Update tests to verify the fix works correctly The bug was that partial() captured _global_loop=None at import time, so cleanup always received None at shutdown instead of the actual LibevLoop instance. This prevented proper cleanup, leaving active callbacks that could crash during Python interpreter shutdown. The fix ensures _global_loop is looked up when atexit calls the cleanup, not when the callback is registered, so cleanup receives the actual loop instance and can properly shut down watchers and join the event loop thread.

The new API queries schema_version from system.local on the connected hosts selected by the requested rack, dc, or cluster scope, respects Cluster.max_schema_agreement_wait and the control-connection metadata timeouts, and bounds the fan-out with configurable parallelism. Update the public Session docs and switch the integration callers that were explicitly waiting on schema agreement to use the session API. Add unit coverage for agreement, retries, busy connections, missing pools, batching, scope filtering, and invalid scope handling. --- cassandra/cluster.py | 193 +++++++++++++++++- docs/api/cassandra/cluster.rst | 2 + tests/integration/long/test_schema.py | 2 +- tests/integration/standard/test_udts.py | 2 +- tests/unit/test_cluster.py | 214 +++++++++++++++++++- tests/unit/test_session_schema_agreement.py | 204 +++++++++++++++++++ 6 files changed, 611 insertions(+), 6 deletions(-) create mode 100644 tests/unit/test_session_schema_agreement.py diff --git a/cassandra/cluster.py b/cassandra/cluster.py index 5e7a68bc1c..b55fbd5172 100644 --- a/cassandra/cluster.py +++ b/cassandra/cluster.py @@ -20,16 +20,17 @@ import atexit import datetime +from enum import Enum from binascii import hexlify from collections import defaultdict from collections.abc import Mapping -from concurrent.futures import ThreadPoolExecutor, FIRST_COMPLETED, wait as wait_futures +from concurrent.futures import Future, ThreadPoolExecutor, FIRST_COMPLETED, wait as wait_futures from copy import copy from functools import partial, reduce, wraps from itertools import groupby, count, chain import json import logging -from typing import Any, Dict, Optional, Union +from typing import Any, Dict, Optional, Union, Tuple from warnings import warn from random import random import re @@ -214,6 +215,14 @@ def __init__(self, message, errors): self.errors = errors +class SchemaAgreementScope(str, Enum): + """Scope selectors for :meth:`.Session.wait_for_schema_agreement`.""" + + RACK = 'rack' + DC = 'dc' + CLUSTER = 'cluster' + + def _future_completed(future): """ Helper for run_in_executor() """ exc = future.exception() @@ -3374,6 +3383,185 @@ def pool_finished_setting_keyspace(pool, host_errors): for pool in tuple(self._pools.values()): pool._set_keyspace_for_all_conns(keyspace, pool_finished_setting_keyspace) + def wait_for_schema_agreement(self, wait_time: Optional[float] = None, + scope: SchemaAgreementScope = SchemaAgreementScope.CLUSTER) -> bool: + """ + Wait for connected hosts in the selected scope to report the same + schema version from ``system.local``. + + By default, the timeout for this operation is governed by + :attr:`~.Cluster.max_schema_agreement_wait` and + :attr:`~.Cluster.control_connection_timeout`. + + Passing ``wait_time`` here overrides + :attr:`~.Cluster.max_schema_agreement_wait`.

00:46:34 -0400 Subject: [PATCH 064/111] control-connection: deprecate ControlConnection.wait_for_schema_agreement Keep ControlConnection.wait_for_schema_agreement() as a compatibility wrapper, but move the existing implementation to _wait_for_schema_agreement() and deprecate the public method in favor of Session.wait_for_schema_agreement(). This lets the control-connection refresh path continue using the old logic internally without emitting warnings. The control-connection wait path was designed for internal metadata refresh use, not as a user-facing schema agreement API. It observes schema agreement from one single node, assuming that schema change statement have been ran on that host. Using it by users will lead to false positives, if user ran statement on a host different from host of control connection. Update the unit tests to call the internal helper everywhere a warning is not expected, add explicit deprecation coverage for the public wrapper, and set stacklevel=2 so the warning points at the caller instead of inside the driver. --- cassandra/cluster.py | 26 ++++++++++++++++++++- tests/unit/test_control_connection.py | 33 +++++++++++++++++++-------- 2 files changed, 48 insertions(+), 11 deletions(-) diff --git a/cassandra/cluster.py b/cassandra/cluster.py index b55fbd5172..483843c2a6 100644 --- a/cassandra/cluster.py +++ b/cassandra/cluster.py @@ -3974,7 +3974,7 @@ def _refresh_schema(self, connection, preloaded_results=None, schema_agreement_w if self._cluster.is_shutdown: return False - agreed = self.wait_for_schema_agreement(connection, + agreed = self._wait_for_schema_agreement(connection=connection, preloaded_results=preloaded_results, wait_time=schema_agreement_wait) @@ -4267,6 +4267,30 @@ def _handle_schema_change(self, event): self._cluster.scheduler.schedule_unique(delay, self.refresh_schema, **event) def wait_for_schema_agreement(self, connection=None, preloaded_results=None, wait_time=None): + """ + Wait for schema agreement from the control connection's metadata view. + + This method is intended for internal metadata refresh flows.

In that mode the driver can still execute queries over the single control connection, but throughput is poor and connection churn increases the chance of request errors.

This caused the driver to fail connecting to ScyllaDB clusters requiring TLS, manifesting as 'protocol version 21 not supported' errors (0x15 = TLS Alert byte misread as protocol version). Fix by using asyncio's native TLS transport (loop.create_connection with ssl= parameter) instead of wrapping sockets with ssl.SSLContext.wrap_socket(). This preserves shard-aware port binding done during _initiate_connection(). Add _AsyncioProtocol to bridge asyncio's transport/protocol API back to Connection.process_io_buffer() for SSL data reads. Non-SSL connections continue using the existing sock_recv path.

If during one libev loop iteration socket gets ready for both read and write, then both watchers will be called. If one decides to close the connection, the other one will still get called anyway.

Sep 17 00:00:00 2001 From: Yaniv Michael Kaul Date: Wed, 13 May 2026 19:56:23 +0300 Subject: [PATCH 095/111] policies: treat SERIAL/LOCAL_SERIAL consistency as LWT for routing Statements with SERIAL or LOCAL_SERIAL consistency level are serialized through the Paxos path on the server, but TokenAwarePolicy only checked is_lwt() (from server prepare metadata) when deciding whether to skip replica shuffling.

That is convenient locally but a footgun in CI, where a test may be silently skipped because a dependency was not installed. The libev unit tests were effectively not running in any CI configuration. Add a CASS_DRIVER_NO_SKIP-gated pytest hook in tests/conftest.py that turns skips into failures (xfail untouched), and enable it in the cibuildwheel test-commands where the C extensions are mandatory (Linux/macOS). Tests that genuinely cannot run in the default configuration are listed explicitly via -k/--ignore (reactor tests run separately per EVENT_LOOP_MANAGER; asyncore, column_encryption and a few upstream-disabled/flaky tests excluded). Add -v to every pytest invocation and install the compress-lz4 extra so the lz4 tests actually run. Pass --import-mode=append in the cibuildwheel pytest commands so the installed compiled wheel takes precedence on sys.path over the in-tree pure-Python cassandra source during wheel tests. Keep the global pytest addopts unchanged so local pytest runs keep their normal import behavior. Windows and PyPy keep no-skip off: the extensions are optional on Windows and are never built on PyPy (setup.py forces is_pypy to skip libev/cmurmur3/Cython), so their extension-dependent skips are legitimate. The PyPy override also drops the compress-lz4 extra (no prebuilt PyPy lz4 wheel), uses cross-shell quoting, and deselects the known PyPy/Windows/macOS-incompatible tests. --- .github/workflows/integration-tests.yml | 2 +- pyproject.toml | 57 +++++++++++++++++++++++-- tests/conftest.py | 36 ++++++++++++++++ 3 files changed, 90 insertions(+), 5 deletions(-) diff --git a/.github/workflows/integration-tests.yml b/.github/workflows/integration-tests.yml index 5e76d6bbb4..acebb1d617 100644 --- a/.github/workflows/integration-tests.yml +++ b/.github/workflows/integration-tests.yml @@ -98,4 +98,4 @@ jobs: if [[ "${{ matrix.python-version }}" =~ t$ ]]; then export PYTHON_GIL=0 fi - uv run pytest tests/integration/standard/ tests/integration/cqlengine/ + uv run pytest -v tests/integration/standard/ tests/integration/cqlengine/ diff --git a/pyproject.toml b/pyproject.toml index 8cffa137f0..698ff4c37b 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -158,22 +158,71 @@ enable = ["pypy"] [tool.cibuildwheel.linux] before-build = "rm -rf ~/.pyxbld && rpm --import https://repo.almalinux.org/almalinux/RPM-GPG-KEY-AlmaLinux && yum install -y libffi-devel libev libev-devel openssl openssl-devel" +# Install the optional lz4 compression dependency so the lz4 segment tests run +# (and fail loudly under CASS_DRIVER_NO_SKIP) instead of skipping silently. +test-extras = ["compress-lz4"] +# Extensions are mandatory on Linux (CASS_DRIVER_BUILD_EXTENSIONS_ARE_MUST=yes), +# so skipping is disabled (CASS_DRIVER_NO_SKIP=1): a missing dependency such as +# libev fails loudly instead of being silently skipped.

Messages carry connection-independent request data; send_body decides the wire format from (protocol_version, protocol_features), so fields belonging to a negotiated protocol extension are emitted exactly on the connections that negotiated it — on every send path, including the control-connection fallback, and without mutating shared message objects per attempt. This is pure plumbing: no message consumes the parameter yet, so no bytes on the wire change. It is groundwork for the SCYLLA_USE_METADATA_ID (#770) and TABLETS_ROUTING_V2 (#913) extensions, which must serialize extension fields based on what the serving connection negotiated. The encode side becomes symmetric with decode_message, which already receives protocol_features. This changes the contracted signature of encode_message: custom protocol handlers overriding it must accept the protocol_features keyword argument. The argument is deliberately required, with no default and no fallback for old-style encoders: extensions are negotiated per connection at STARTUP before the per-request handler is known, so an encoder unaware of protocol_features could silently omit fields a negotiated extension requires; omitting it fails fast with TypeError instead. Tests: send_msg hands the connection's features to the encoder; encode_message forwards them into send_body (plain and compressed paths) and raises TypeError when the argument is omitted; a byte-identity suite pins frames for representative messages (v3/v4/v5) to the exact bytes produced before this change, both without features and with all-default features.

When negotiated, the server includes a hash of the result metadata in the PREPARE response; the driver sends it back with every EXECUTE, allowing the server to omit result metadata from responses (skip_meta) and to report schema changes with METADATA_CHANGED plus fresh metadata, which the driver adopts automatically. protocol_features.py: parse the extension from SUPPORTED, echo it in STARTUP, expose it as ProtocolFeatures.use_metadata_id. protocol.py: ExecuteMessage carries connection-independent request data (skip_meta, result_metadata_id) fixed at construction; serialization decides the wire format from the (protocol_version, protocol_features) that Connection.send_msg supplies for the serving connection: - The metadata-id field is written iff the connection speaks CQL v5+ or negotiated the extension - always, on such connections. An empty sentinel (b'') is written when the statement has no id (prepared before the extension was active, e.g. during a rolling upgrade, or an LWT statement): the sentinel mismatch makes the server respond with METADATA_CHANGED plus the current id and metadata, so such statements acquire an id on their first execution. This also fixes a TypeError on v5 when result_metadata_id was None. - _SKIP_METADATA_FLAG is written only when the SCYLLA_USE_METADATA_ID extension is negotiated on the connection; without the metadata-id mechanism a schema change after PREPARE would leave the driver decoding rows with stale cached metadata. This is deliberately narrower than the metadata-id field above: on native CQL v5 the field is part of the frame layout, but the driver does not request skip there. Upstream never emitted _SKIP_METADATA_FLAG on any version (_write_query_params never wrote it), and enabling the skip optimization for native v5 is a separate change kept out of scope for this Scylla extension. Because messages are immutable after construction, every send path is correct without per-path setup - including the control-connection fallback - and concurrent sends of the same message (speculative executions) cannot race on per-connection state. query.py: PreparedStatement stores (result_metadata, result_metadata_id) as one tuple replaced in a single attribute assignment, read through compatibility properties and updated via update_result_metadata(). Response callbacks update statements while request threads read them; a torn pair (fresh id + stale metadata) would make the server skip sending metadata while rows are decoded against the wrong columns, with no recovery. The compatibility setters are documented as non-atomic relative to each other - update_result_metadata() is the atomic path; the setters exist only for callers assigning the old individual attributes. cluster.py: _create_response_future snapshots the pair once and requests skip_meta only when the statement has both an id and usable cached metadata (result_metadata is None for NO_METADATA/LWT statements and [] for zero-column statements; neither can nor needs to skip metadata). The same snapshot is handed to the ResponseFuture, so a skip_meta response is decoded against the metadata that pairs with the id the message sent - not a later re-read of the statement cache, which a concurrent METADATA_CHANGED could have replaced between construction and send (and which also keeps speculative sends of one message internally consistent). _set_result adopts a METADATA_CHANGED response by replacing the pair atomically; a response carrying a new id without column metadata is ignored with a warning, since adopting the id alone would create the unrecoverable stale-decode state. skip_meta additionally stays off for continuous paging (@dkropachev): Connection.process_msg hardcodes result_metadata=None for every page after the first, since it isn't threaded through the paging session - a skip_meta response has nothing to decode page 2+ against, and would crash on it. _execute_after_prepare refreshes the pair from exactly what the reprepare response carries, including the id (@dkropachev): falling back to the previously cached id when the response has none risks pairing it with metadata from a different schema version than the one that id was computed for - e.g. if the schema changed and then reverted between the two PREPAREs, the old id can become valid again for the current schema while paired locally with an intermediate version's metadata, with no server-side mismatch to catch it. Dropping it instead lets the next id-aware execute re-acquire a correctly paired id through the same b'' sentinel self-healing path a never-prepared statement uses. docs/scylla-specific.rst: documents the extension and its behaviour, worded so the skip_meta optimization reads as conditional on the extension being negotiated rather than pre-existing default behaviour.

Without change detection this would be unsafe: if +the table schema changes after a statement is prepared (e.g., a column is added, +removed, or its type is altered), the cached metadata becomes stale — leading to +decoding errors or incorrect data. + +ScyllaDB solves this by backporting the ``metadata_id`` mechanism from CQL native +protocol v5 as a v4 extension: ``SCYLLA_USE_METADATA_ID``. When this extension is +negotiated, the server includes a hash of the result metadata in the ``PREPARE`` +response. The driver sends this hash back with every ``EXECUTE`` request. If the +schema has changed, the server sets the ``METADATA_CHANGED`` flag and returns the +new metadata hash together with the updated column definitions. The driver +automatically updates its cache and uses the new metadata to decode the current +response — all transparently, with no application code change required. + +**Behaviour summary:** + +- Automatically negotiated at connection time when the ScyllaDB node supports it. +- ``skip_meta`` is enabled (metadata omitted from EXECUTE responses) only when it + is safe: the prepared statement must carry both a ``result_metadata_id`` and + usable cached result metadata from PREPARE, *and* the connection serving the + request must have negotiated ``SCYLLA_USE_METADATA_ID`` — decided per + connection when the request is serialized. +- Plain CQL v5 connections are unaffected: the metadata id is part of the native + v5 EXECUTE frame layout and is still sent, but the driver does not request + skip-metadata there, so such connections keep receiving full result metadata. +- When a schema change is detected by the server, the driver refreshes both the + cached column metadata and the metadata hash for that prepared statement so that + all subsequent executions benefit immediately. +- Statements prepared before the extension was negotiated (e.g., during a rolling + upgrade) start without a metadata hash, but acquire one automatically: on their + first execution over a connection with the extension, the driver sends an empty + hash, the server detects the mismatch and responds with the current hash and + full metadata, and the driver caches both. Subsequent executions get the + ``skip_meta`` optimization — no re-prepare or client restart is needed. + +**Current scope:** the optimization applies to any prepared statement that has +non-empty cached result columns — in practice, SELECT queries. +UPDATE/INSERT/DELETE statements naturally return no result columns, so +their ``result_metadata`` is always empty and ``skip_meta`` is never set for +them. There is no code-level restriction to SELECT; the behaviour follows +directly from the data. + +For full protocol details see the ScyllaDB CQL protocol extensions documentation: +https://github.com/scylladb/scylladb/blob/master/docs/dev/protocol-extensions.md From b8b714ca31782f2f527c108b10b92538887788c0 Mon Sep 17 00:00:00 2001 From: Mikita Hradovich Date: Tue, 21 Jul 2026 15:26:00 +0200 Subject: [PATCH 109/111] DRIVER-153: tests for SCYLLA_USE_METADATA_ID extension Unit tests for the extension across its layers: test_protocol_features.py: SCYLLA_USE_METADATA_ID parsed from SUPPORTED and echoed in STARTUP options; absent by default. test_protocol.py (wire format): - metadata-id field written on v4 iff the connection negotiated the extension, with the exact bytes asserted; empty sentinel (b'') when the statement has no id, on both the extension path (v4) and the v5 native path (previously a TypeError); - _SKIP_METADATA_FLAG written when skip_meta is requested and the SCYLLA_USE_METADATA_ID extension is negotiated (v4 or v5), and NOT set on a native v5 connection without the extension (the id field is still written there, but the driver does not request skip); also suppressed - together with the id field - on a v4 connection without the extension, even when the statement carries an id; - PREPARED response decoding reads result_metadata_id iff the extension was negotiated (or v5); METADATA_CHANGED/NO_METADATA flag handling. test_query.py: PreparedStatement stores the (result_metadata, result_metadata_id) pair atomically - constructor, update_result_metadata, and the backwards-compatible single-attribute setters all replace the pair as one unit, and previously-taken snapshots stay internally consistent. test_response_future.py: - _create_response_future builds ExecuteMessage from a single pair snapshot: skip_meta only with both an id and usable cached metadata; disabled for id-less statements, NO_METADATA/LWT statements (result_metadata None) and zero-column statements (result_metadata []), while the id still rides on the message; - _query sends the message exactly as constructed (no per-connection mutation - regression test for the speculative-execution race) and decodes a skip_meta response against the metadata snapshotted when the message was built, not a later read of the statement cache (regression for a concurrent METADATA_CHANGED racing the send); - _set_result METADATA_CHANGED path replaces the cached pair atomically; a response with a new id but no column metadata (empty or absent) is ignored with a warning, leaving the cached pair unchanged - adopting the id alone would poison the cache with a stale-metadata/current-id pair the server would never refresh; - _execute_after_prepare refreshes the pair from exactly what the reprepare response carries, including the id, and no longer keeps the previous id when the response has none (@dkropachev: doing so risked pairing a stale id with metadata from a different schema version - test_execute_after_prepare_no_metadata_id_in_response_clears_id); - a statement with valid cached metadata+id must still get skip_meta=False when continuous_paging_options is set (@dkropachev: Connection.process_msg hardcodes result_metadata=None for paging-session pages after the first, so a skip_meta response would crash decoding them - test_create_execute_message_continuous_paging_disables_skip_meta). tests/integration/standard/test_scylla_metadata_id.py: live-server coverage against a real Scylla node via CCM, closing the one gap unit tests can't - whether Scylla actually treats the empty result_metadata_id sentinel as a mismatch rather than a protocol error. Confirms extension negotiation, the normal METADATA_CHANGED-after-ALTER-TABLE path, and the sentinel round trip: a statement forced back to result_metadata_id=None (simulating one prepared before the extension was known, e.g. mid rolling-upgrade) executes without error and comes back with a fresh id. Mirrors the equivalent live test already merged in the Java driver (scylladb/java-driver#758, should_handle_empty_metadata_id_when_executing_statement_when_supported).

The cache is keyed by id(column_metadata). For prepared statements the result_metadata list is stored on PreparedStatement and reused, so id() is stable. On cache hit we verify object identity (cached_ref is column_metadata) and that session-level settings (column_encryption_policy, protocol_version) still match. Implementation details: - _get_or_build_parse_desc: cached path, used only when column_metadata comes from result_metadata (prepared statements with stable id()). - _build_parse_desc: uncached path, used for inline metadata from non-prepared queries that creates a fresh list every execution. - Cache is bounded to 256 entries; cleared entirely when full. - Returns only (desc, column_names, column_types) to the caller, avoiding exposure of internal cache fields. - Thread-safety: dict get/set are atomic in CPython (GIL), but concurrent cache misses may cause redundant construction (benign). A clear_parse_desc_cache() and get_parse_desc_cache_size() function are exposed for testing. ## Benchmark results (median, pytest-benchmark) ### ParseDesc construction only (reference benchmarks) | Columns | **Before** (original) | **After** (with cache) | |---------|-----------------------|------------------------| | 5 cols | 3,966 ns | 191 ns | | 10 cols | 5,730 ns | 175 ns | | 20 cols | 9,266 ns | 166 ns | | 50 cols | 19,388 ns | 193 ns | ### Full pipeline integration (recv_results_rows through Cython) | Scenario | **Before** (original) | **After** (with cache) | |-------------------|-----------------------|------------------------| | 1 row x 10 col | 40,867 ns | 2,977 ns | | 100 rows x 5 col | 145,584 ns | 73,206 ns | | 1000 rows x 5 col | 1,099,825 ns | 999,517 ns | For small result sets (single-row lookups common with prepared statements), ParseDesc construction is a large fraction of the total response-path cost.
