Apache Spark reassigned SPARK-38178:
------------------------------------
Assignee: Apache Spark
> Correct the logic to measure the memory usage of RocksDB
> --------------------------------------------------------
>
> Key: SPARK-38178
> URL: https://issues.apache.org/jira/browse/SPARK-38178
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.2.1
> Reporter: Yun Tang
> Assignee: Apache Spark
> Priority: Major
>
> Currently, structed streaming would report the memory usage of RocksDB as
> state store's metrics. However, it only sums from
> {{rocksdb.estimate-table-readers-mem}} and {{rocksdb.size-all-mem-tables}}.
> However, this lacks of the memory usage of block cache. (You can refer to
> [Memory-usage-in-RocksDB](https://github.com/facebook/rocksdb/wiki/Memory-usage-in-RocksDB)
> for more details.)
> BTW, as the "block-cache-pinned-usage" is included in "block-cache-usage", we
> don't need to include the pinned usage.
