--------------------------------
Summary: Enable FRocksDB to optimize performance via options when
bounding total memory
Key: FLINK-14877
URL: https://issues.apache.org/jira/browse/FLINK-14877
Project: Flink
Issue Type: Sub-task
Reporter: Yun Tang
Fix For: 1.10.0
Currently, as we plan to keep base on RocksDB-5.17.2 and cherry-pick
write-buffer manager related rocksJava commits to FRocksDB. Options below are
recommend when bounding the total memory.
{code:java}
tableConfig.setCacheIndexAndFilterBlocksWithHighPriority(true);
tableConfig.setPinTopLevelIndexAndFilter(true);
{code}
However, RocksDB-5.17.2 does not include these java API. But luckily, these
features are already implemented on RocksDB's native code. Cherry pick
https://github.com/facebook/rocksdb/pull/4589 with only updates on java side
should be enough.
