From 19158afd59ee83ce29613a7da5597477f6b49d8e Mon Sep 17 00:00:00 2001 From: liudezhi Date: Tue, 20 Jan 2026 15:24:05 +0800 Subject: [PATCH 1/7] [feat][managed-ledger] Add custom ledger trim functionality MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add ability to trim consumed ledgers before a specified ledger ID. Changes: - Add `asyncTrimConsumedLedgersBefore(long ledgerId)` method to ManagedLedger interface - Add protected factory method `createManagedLedgerInstance()` to ManagedLedgerFactoryImpl to allow subclass extension - Make several methods/fields protected in ManagedLedgerImpl to enable extension access (metadataMutex, trimmerMutex, invalidateReadHandle, isOffloadedNeedsDelete, etc.) - Create new managed-ledger-ext module with: - ManagedLedgerImplExt: Extended implementation with custom trim logic - ManagedLedgerFactoryImplExt: Factory that creates ManagedLedgerImplExt instances - ManagedLedgerClientFactoryExt: Storage implementation for Pulsar integration This allows users to manually trigger ledger deletion before a specified ledger ID, provided all ledgers before that ID have been fully consumed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- managed-ledger-ext/pom.xml | 90 +++++ .../ext/ManagedLedgerClientFactoryExt.java | 181 ++++++++++ .../ext/ManagedLedgerFactoryImplExt.java | 64 ++++ .../mledger/ext/ManagedLedgerImplExt.java | 320 ++++++++++++++++++ .../bookkeeper/mledger/ManagedLedger.java | 14 + .../impl/ManagedLedgerFactoryImpl.java | 27 +- .../mledger/impl/ManagedLedgerImpl.java | 18 +- pom.xml | 1 + 8 files changed, 702 insertions(+), 13 deletions(-) create mode 100644 managed-ledger-ext/pom.xml create mode 100644 managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerClientFactoryExt.java create mode 100644 managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerFactoryImplExt.java create mode 100644 managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerImplExt.java diff --git a/managed-ledger-ext/pom.xml b/managed-ledger-ext/pom.xml new file mode 100644 index 0000000000000..266c3e5ceebd0 --- /dev/null +++ b/managed-ledger-ext/pom.xml @@ -0,0 +1,90 @@ + + + + 4.0.0 + + org.apache.pulsar + pulsar + 3.0.16-SNAPSHOT + .. + + + managed-ledger-ext + Managed Ledger Extension + Extension for Managed Ledger with custom trim capabilities + + + + + ${project.groupId} + managed-ledger + ${project.version} + + + + + ${project.groupId} + pulsar-metadata + ${project.version} + + + + + org.apache.bookkeeper + bookkeeper-server + + + + + org.slf4j + slf4j-api + + + + + org.testng + testng + test + + + ${project.groupId} + pulsar-broker-common + ${project.version} + compile + + + ${project.groupId} + pulsar-broker + ${project.version} + compile + + + + + + + org.apache.maven.plugins + maven-compiler-plugin + + + + diff --git a/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerClientFactoryExt.java b/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerClientFactoryExt.java new file mode 100644 index 0000000000000..27755b9cd3b26 --- /dev/null +++ b/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerClientFactoryExt.java @@ -0,0 +1,181 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add a new method to trim consumed ledgers before a specific ledger ID, allowing more precise control over ledger cleanup than the existing retention-based trimming. Key features: - Trim all consumed ledgers before a specified ledger ID - Handle edge cases: large IDs, gap IDs, small IDs - Protection against unconsumed data via slowest reader check - Automatic boundary adjustment when ID equals current ledger Changes: - Add ManagedLedgerImplExt class extending ManagedLedgerImpl - Implement asyncTrimConsumedLedgersBefore method - Add comprehensive test coverage (9 test cases) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- managed-ledger-ext/pom.xml | 167 ++++- .../mledger/ext/ManagedLedgerImplExt.java | 99 ++- .../mledger/ext/ManagedLedgerImplExtTest.java | 621 ++++++++++++++++++ 3 files changed, 841 insertions(+), 46 deletions(-) create mode 100644 managed-ledger-ext/src/test/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerImplExtTest.java diff --git a/managed-ledger-ext/pom.xml b/managed-ledger-ext/pom.xml index 266c3e5ceebd0..842ecd5999745 100644 --- a/managed-ledger-ext/pom.xml +++ b/managed-ledger-ext/pom.xml @@ -39,51 +39,188 @@ managed-ledger ${project.version} + + + ${project.groupId} + managed-ledger + ${project.version} + test-jar + test + - ${project.groupId} - pulsar-metadata + pulsar-broker ${project.version} - + + ${project.groupId} + pulsar-broker-common + ${project.version} + + + org.apache.bookkeeper bookkeeper-server - + + + + org.apache.bookkeeper.stats + prometheus-metrics-provider + + - org.slf4j - slf4j-api + org.apache.bookkeeper.stats + codahale-metrics-provider + ${bookkeeper.version} + + + amqp-client + com.rabbitmq + + - - org.testng - testng - test + com.google.protobuf + protobuf-java + ${project.groupId} - pulsar-broker-common + pulsar-common ${project.version} - compile + ${project.groupId} - pulsar-broker + pulsar-metadata ${project.version} - compile + + + + com.google.guava + guava + + + + ${project.groupId} + testmocks + ${project.version} + test + + + + org.apache.zookeeper + zookeeper + tests + test + + + ch.qos.logback + logback-core + + + ch.qos.logback + logback-classic + + + io.netty + netty-tcnative + + + + + org.roaringbitmap + RoaringBitmap + + + io.dropwizard.metrics + metrics-core + test + + + org.xerial.snappy + snappy-java + test + + + + org.awaitility + awaitility + test + + + + org.slf4j + slf4j-api + + org.gaul + modernizer-maven-plugin + + true + 17 + + + + modernizer + verify + + modernizer + + + + + + + org.apache.maven.plugins + maven-jar-plugin + + + + test-jar + + + + + + org.xolstice.maven.plugins + protobuf-maven-plugin + ${protobuf-maven-plugin.version} + + com.google.protobuf:protoc:${protoc3.version}:exe:${os.detected.classifier} + true + + + + generate-sources + + compile + + + + org.apache.maven.plugins - maven-compiler-plugin + maven-checkstyle-plugin + + + checkstyle + verify + + check + + + diff --git a/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerImplExt.java b/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerImplExt.java index 364a3d7da6765..b2406cc49810d 100644 --- a/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerImplExt.java +++ b/managed-ledger-ext/src/main/java/org/apache/bookkeeper/mledger/ext/ManagedLedgerImplExt.java @@ -103,10 +103,43 @@ private void internalTrimConsumedLedgersBefore(long ledgerId, CompletableFuture< List offloadedLedgersToDelete = new ArrayList<>();
