From cb590e429eebae9f4f3420531036fec429b897e3 Mon Sep 17 00:00:00 2001 From: Socrates Date: Wed, 22 Jul 2026 11:03:13 +0800 Subject: [PATCH 01/19] [feature](paimon) Add Paimon write support via JNI Issue Number: None Related PR: #65381 Problem Summary: Doris 4.1 can read Paimon external tables but does not have a write path. This backport adds INSERT INTO and INSERT OVERWRITE through a JNI bridge to the Paimon Java SDK, including planner and transaction integration, type conversion, partitioned writes, commit and abort handling, outcome reconciliation, and Doris-managed spill paths. The backport preserves the branch-4.1 JDBC-specific sink and FileSystemProvider APIs while adapting the Paimon sink plan copies to the branch-4.1 Nereids interfaces. Add Paimon external table write support through JNI. - Test: Unit Test - `./build.sh --fe --be-java-extensions` - `./run-fe-ut.sh --run org.apache.doris.datasource.paimon.PaimonTransactionTest,org.apache.doris.paimon.PaimonJniWriterTest,org.apache.doris.nereids.parser.ParseInsertPartitionSpecTest` - `JAVA_TOOL_OPTIONS="--add-opens=java.base/java.nio=ALL-UNNAMED" ./run-fe-ut.sh --run org.apache.doris.paimon.PaimonJniWriterTest` - Behavior changed: Yes, Paimon external tables support INSERT INTO and INSERT OVERWRITE - Does this need documentation: No --- be/src/exec/operator/operator.cpp | 3 + .../operator/paimon_table_sink_operator.cpp | 39 ++ .../operator/paimon_table_sink_operator.h | 104
