> 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
> Assignee: Yun Tang
> Priority: Major
> 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.
