Add span-derived primary tags (CSS v1.3.0) by dougqh · Pull Request #11402 · DataDog/dd-trace-java

dougqh · 2026-05-18T14:37:04Z

What Does This Do

Implements span-derived primary tags (Client-Side Stats v1.3.0): users configure DD_TRACE_STATS_ADDITIONAL_TAGS to extract matching span tag values as additional aggregation dimensions on ClientGroupedStats.AdditionalMetricTags.

Motivation

From the RFC...

Users may want to aggregate APM statistics by custom dimensions beyond the standard primary tag (typically env). For example, a user might want stats grouped by region, tenant_id, or other business-relevant span tags. This enables more granular visibility into service performance across different segments.

Configuration

This feature is experimental and must be explicitly opted in.

Environment Variable	System Property	Default	Description
`DD_TRACE_EXPERIMENTAL_FEATURES_ENABLED`	`dd.trace.experimental.features.enabled`	(none)	Required to enable this feature. Set to `DD_TRACE_STATS_ADDITIONAL_TAGS` (comma-separate to enable multiple experimental features).
`DD_TRACE_STATS_ADDITIONAL_TAGS`	`dd.trace.stats.additional.tags`	(none)	Comma-separated span tag keys to use as additional aggregation dimensions. Max 4 keys; excess dropped at startup with a warn log.
`DD_TRACE_STATS_ADDITIONAL_TAGS_CARDINALITY_LIMIT`	`dd.trace.stats.additional.tags.cardinality.limit`	`100`	Per-key distinct-value cap per reporting cycle. Values beyond the cap are reported as `tracer_blocked_value`.

Minimal configuration to enable:

DD_TRACE_EXPERIMENTAL_FEATURES_ENABLED=DD_TRACE_STATS_ADDITIONAL_TAGS
DD_TRACE_STATS_ADDITIONAL_TAGS=region,tenant_id

Additional Notes

Design

Wire format: new AdditionalMetricTags field on ClientGroupedStats, emitted as repeated string of "<key>:<value>" entries (mirrors PeerTags). Schema-ordered (alphabetical by key); null slots skipped; field omitted when empty, so unconfigured deployments pay zero payload overhead.

Cardinality protection — three caps, matching the .NET implementation:

MAX_ADDITIONAL_TAG_KEYS = 4 — configured-key count cap; excess keys dropped at startup with a warn log.
Per-value length cap (200 chars) — values exceeding this are replaced with tracer_blocked_value.
DD_TRACE_STATS_ADDITIONAL_TAGS_CARDINALITY_LIMIT (default 100) — per-key distinct-value cap per reporting cycle; further new values collapse to the "<key>:tracer_blocked_value" sentinel.

Threading: all canonicalization (UTF8BytesString interning, cardinality limiting) runs on the aggregator thread. The producer path captures raw String values into a String[] parallel to the schema — no sync on the hot path.

Tests

Migrated SerializingMetricWriterTest from Spock/Groovy to JUnit 5 Java and folded the additional-tags coverage into its shared ValidatingSink — one msgpack-decode harness instead of two.

Benchmark

AdditionalTagsMetricsBenchmark.publish (JMH, Java 17, 8 threads, @Fork(1)):

`limitsEnabled`	throughput
`false`	22.3M ± 0.7M ops/s
`true`	6.9M ± 1.4M ops/s

The true arm is slower because it records more — over-cardinality values collapse into the tracer_blocked_value sentinel — not because limiting itself is expensive.

… create() Replace Support.MAX_RATIO_NUMERATOR / _DENOMINATOR with a single float MAX_RATIO constant, and add a Support.create(int, float) overload that takes a scale factor. Callers now write Support.create(n, MAX_RATIO) instead of stitching together the int arithmetic at the call site. The scaled size is truncated (not ceiled) before going through sizeFor. sizeFor already rounds up to the next power of two, so truncation just absorbs float fuzz that would otherwise push a result like 12 * 4/3 = 16.0000005f past 16 and double the bucket array size for no reason. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Five small cleanups from a design re-review pass: 1. Support javadoc: drop the stale "methods are package-private" sentence; most of them were made public in earlier commits for higher-arity callers. Also drop the "nested BucketIterator" framing (iterators are peers of Support inside Hashtable, not nested inside Support). 2. MAX_RATIO javadoc: drop the Math.ceil recommendation; create(int, float) deliberately truncates and is the canonical pathway. 3. Document the null-hash treatment on D1.Entry.hash and D2.Entry.hash so the behavior difference is explicit: D1 uses Long.MIN_VALUE as a sentinel that's collision-free against any int-valued hashCode(); D2 has no such sentinel and relies on matches() to resolve null/null vs hash-0 collisions. 4. Rename Support.MAX_CAPACITY -> MAX_BUCKETS and sizeFor's parameter to requestedSize. The cap is on the bucket-array length, not entry count; the new name reflects that. Error messages updated to match. 5. Drop the `abstract` modifier on Hashtable in favor of `final` with a private constructor. Nothing actually subclasses Hashtable -- the abstract was a namespace device that read as "intended for extension." Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

- Add Support.insertHeadEntry(buckets, long keyHash, entry) overload that derives the bucket index itself. Callers that already have a hash but not the index (the common case) now avoid the redundant bucketIndex(...) hop. - D1.insert, D1.insertOrReplace, D2.insert, D2.insertOrReplace: use the new overload, drop the (thisBuckets local, bucketIndex compute, setNext, store) sequence at each call site. - D2.buckets: drop the `private` modifier to match D1.buckets. Both are package-private so iterator tests in the same package can drive Support.bucketIterator against the table's bucket array. Added a short comment on both fields documenting the rationale. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Three follow-ups from the design review: - Make Hashtable.Entry.next private. All same-package readers (BucketIterator) already had a next() accessor; the leftover direct field reads now route through it. Closes the "mixed encapsulation" gap where some readers used the accessor and same-package ones reached for the field. - BucketIterator and MutatingBucketIterator now document that chain-walk work happens in next() (and the constructor for the first match); hasNext() is an O(1) field read. - Add D1.getOrCreate(K, Function) and D2.getOrCreate(K1, K2, BiFunction). Both reuse the lookup hash for the insert on miss, avoiding the double-hash that "get; if null then insert" callers would otherwise pay. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Addresses PR #11409 review comments: - #3267164119 / #3267165525: wrap every single-line if/break body in braces (7 sites across BucketIterator, MutatingBucketIterator, and the full-table Iterator). - #3275947761 / #3275948108 (sarahchen6): null out the removed/replaced entry's next pointer after splicing it out of the chain in MutatingBucketIterator.remove / .replace. Applied the same fix to the full-table Iterator.remove for consistency. Rationale: detaching prevents accidental traversal through a removed entry via a stale reference and lets the GC reclaim a chain tail that the removed entry was the last referrer to.

…sistency Addresses PR #11409 review comment #3276167001. The method parallels the primitive hash(boolean) / hash(int) / hash(long) / ... family, so naming it hash(Object) -- with null collapsing to Long.MIN_VALUE as a sentinel distinct from any real hashCode -- matches the rest of the public surface. Test call sites that pass a literal null now disambiguate against hash(int[]) / hash(Object[]) / hash(Iterable) via an (Object) cast.

Addresses sarahchen6's review comment on ConflatingMetricsAggregator extractPeerTagPairs: replaces the worst-case-allocation + trim-and-copy flat-pairs layout with a parallel-array carrier. - New PeerTagSchema: minimal carrier of String[] names. Two flavors -- a static INTERNAL singleton (one entry: base.service) for internal-kind spans, and per-discovery built schemas for client/producer/consumer spans. Deliberately no cardinality limiters or per-cycle state; that layers on top in a later PR. - ConflatingMetricsAggregator: caches the peer-aggregation schema keyed on reference equality of features.peerTags() -- a single volatile read + a long compare on the steady-state producer hot path, no allocation. The producer now captures only a String[] of values parallel to the schema's names; the schema reference is carried on SpanSnapshot. The prior "build worst-case pairs then trim" code is gone. - SpanSnapshot: replaces String[] peerTagPairs with PeerTagSchema + String[] peerTagValues. Producer drops the schema reference if no values fired so the consumer short-circuits on null. - Aggregator.materializePeerTags: now reads name/value pairs at the same index from (schema.names, snapshot.peerTagValues). Counts hits once for exact-size allocation; preserves the singletonList fast path for the common one-entry case (e.g. internal-kind base.service). Producer-side cost goes from "allocate String[2n] + walk + maybe trim" to "single volatile read + walk + lazy String[n] only on first hit".

- Aggregator.materializePeerTags: fold the firstHit-discovery nested if into a single guarded post-increment (amarziali, #3279243138). One body line: `if (values[i] != null && hitCount++ == 0) firstHit = i;`. - Drop redundant isKind(SpanKindFilter) overrides in both TraceGenerator.groovy files (amarziali, #3279264553 / #3279382648). CoreSpan.java:84 already supplies a default implementation that reads the same span.kind tag. - Bump TRACER_METRICS_MAX_PENDING default from 2048 -> 131072 to address the capacity regression amarziali flagged (#3279378375). Without producer-side conflation, the inbox now holds 1 SpanSnapshot per metrics-eligible span instead of 1 conflated Batch per ~64 spans; restoring effective capacity parity (~2048 * ~64 = 131072) prevents a ~64x rise in inbox-full drops at the same span rate. ~100 B per SpanSnapshot puts the worst-case heap floor at ~13 MB -- bounded.

Addresses PR #11381 review (amarziali, #3279325340 -- "Are the existing tests covering this case?"). New ConflatingMetricsAggregatorInboxFullTest constructs the aggregator with a small inbox (queueSize=8), deliberately does NOT call start() so the consumer thread never drains, then publishes enough spans to overflow the inbox. Verifies that healthMetrics.onStatsInboxFull() is called at least once -- the fast-path's `inbox.size() >= inbox.capacity()` short-circuit triggers when the producer-side queue is at capacity. Test is Java + JUnit 5 + Mockito per the project convention for new tests; uses a CoreSpan Mockito mock rather than the SimpleSpan Groovy fixture so we don't depend on Groovy-then-Java compile order from the test source set. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…read Addresses amarziali's review comment #3279340181 ("It would be more efficient to trigger from the other side"). The producer-side reference compare on every publish goes away; the aggregator thread reconciles the cached schema against feature discovery once per reporting cycle. - DDAgentFeaturesDiscovery: expose getLastTimeDiscovered() so callers can detect a discovery refresh without copying the peerTags Set. - PeerTagSchema: add `long lastTimeDiscovered` (plain, aggregator-only) and `hasSameTagsAs(Set)`. of(Set, long) takes the timestamp; INTERNAL uses a -1L sentinel since it's never reconciled. - ConflatingMetricsAggregator: * Drop the cachedPeerTagsSource volatile and the per-publish reference compare. * Producer fast path is now `cachedPeerTagSchema` volatile read + null-check; first publish takes the one-time synchronized bootstrap. * Add reconcilePeerTagSchema() that runs once per cycle on the aggregator thread: fast-path timestamp compare, slow-path set compare, bump-in-place when the set is unchanged. - Aggregator: new `Runnable onReportCycle` constructor parameter, run at the start of report() (before the flush, so any test awaiting writer.finishBucket() observes the schema in its post-reconcile state and so the next publish sees the new schema without a handoff). - Update "should create bucket for each set of peer tags" to drive two reporting cycles separated by a report() that triggers reconcile. The old test relied on per-publish reference detection, which the new design intentionally doesn't preserve -- the schema is now stable within a cycle.

Addresses round-3 review nice-to-haves on PR #11381. - PeerTagSchemaTest: unit coverage for hasSameTagsAs() (the predicate that drives the reconcile fast/slow path split), the of(Set, long) factory, and the INTERNAL singleton. The hasSameTagsAs cases include same-content-different-Set-reference (the case the reconcile fast path relies on after a discovery refresh) and content-mismatch in either direction. - ConflatingMetricsAggregatorBootstrapTest: integration coverage for the producer-side bootstrap + aggregator-thread reconcile flow. * bootstrapHappensOnceOnFirstPublish -- three publishes against an un-started aggregator (no consumer thread, no reconciles); verifies features.peerTags() and features.getLastTimeDiscovered() are each called exactly once. * reconcileSkipsDeepCompareWhenTimestampMatches -- two cycles with constant features.getLastTimeDiscovered(); each post-report reconcile short-circuits on the timestamp fast path, so peerTags() is called only by bootstrap (1 total). * reconcileSurvivesTimestampBumpWhenTagsUnchanged -- timestamps bump every reconcile, forcing the slow set-compare path; the tag set stays identical, so the schema is preserved and continues to flush buckets correctly across cycles.

A mis-set trace.stats.<tag>.cardinality.limit flowed straight into TagCardinalityHandler, which eagerly allocates four reference arrays of nextPow2(limit * 2) slots. A large value could exhaust the heap while the aggregator is constructed, before the tracer finished starting. Cap the accepted value at 1 << 16 (~2 MB per handler worst case, far above the largest built-in default of 1024) and fall back to the default with a warning when it is exceeded, mirroring the existing <= 0 fallback.

Codex review resolution (base-branch findings)

Codex surfaced these while reviewing the stacked PRs (#12069/#12070); they concern this base branch, so tracking their resolution here.

Fixed

Finding	Resolution
Bound the configurable additional-tag / stats cardinality limit (P1)	`Config.getTraceStatsCardinalityLimit` now caps the value at `1 << 16` and falls back to the default with a warning above that, mirroring the existing `<= 0` fallback, so a mis-set limit can no longer throw or exhaust the heap during aggregator construction. — `4188b43471`
Snapshot the additional-tags configuration in `Config` (P1/P2)	Resolved once into a `final` field at construction, returned by the getter, and included in `toString()`, per the add-new-configuration convention. No more per-call `ConfigProvider` re-query or invisibility when no aggregator is built. — `f5b083bd80` (+ tests `86896d7ce3`)
Remove the unused `AggregateEntry.recordDurations` helper (P3)	Removed along with its now-orphaned `AtomicLongArray` import; no callers in any source tree. — `976d335d7a`

Working as intended / acceptable by design

Cap the combined additional-tag cardinality (P1) — The per-key budgets intentionally don't bound the product; the aggregate table does. AggregateTable caps rows (2048 normal / 256 tight-heap); once full, Aggregator.findOrInsert returns null and the span is dropped via healthMetrics.onStatsAggregateDropped(), reported under datadog.tracer.stats.collapsed_spans tagged collapsed:whole_key. So aggregate cardinality is bounded by the table cap regardless of the per-key product, and overflow is observable rather than silent. A shared tuple budget would only move the same cap earlier and lose the per-key collapsed:/oversized: attribution.

Retain retired peer-tag schemas until producers release them (P2) — The one-cycle previousPeerTagSchema retention covers the normal straggler (a producer that read the old schema just before a discovery-driven change). The residual window described requires a producer stalled beyond a full reporting intervaland a coinciding rare discovery tag change; even then only the collapse counter for that one straggler span is lost, never its aggregate contribution — and there was always fundamentally a race with the config update itself. Deemed negligible. Full mechanical write-up in #11402 (comment).

Deferred

Move the new unit test to JUnit 5 (P1) — Agreed on the standing convention. The added coverage extends the existing ClientStatsAggregatorTest.groovy Spock suite rather than introducing a standalone test; a full JUnit 5 migration of that large suite is a mechanical change tracked separately, out of scope for this PR.

Removing recordDurations took away the only AtomicLongArray access touching the recording counters, so SpotBugs no longer raises the AT_* atomicity warnings on recordOneDuration and clearAggregate. Their @SuppressFBWarnings annotations are now flagged as US_USELESS_SUPPRESSION; remove them (and the orphaned import). The single-writer invariant they documented remains described in the class javadoc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
