About Apache RocketMQ
The RocksDB migration reaches native code as the legacy DLedger broker mode is marked for removal
The 5.x line continues to replace storage internals with RocksDB and to retire the mechanisms it supersedes. 5.5.1, the first release since April, swaps the pure-Java ConsumeQueue compaction filter for a native RocksDB CqCompactionFilter behind a cross-platform JNI shim, drops the shaded rocketmq-rocksdb dependency, and deprecates the legacy Broker DLedger mode. Lite Mode, introduced in 5.5.0, received stability work rather than the client-side adoption path it still needs. Alongside this sit fastjson 1.x removal and a long list of Proxy, Pop and Remoting fixes.
