----------------------------------
Issue Type: Improvement (was: Bug)
> Consider not to Treat Mixed Usage of Shared and Dedicated Block Caches among
> RocksDB State Stores as Illegal State
> ------------------------------------------------------------------------------------------------------------------
>
> Key: KAFKA-12223
> URL: https://issues.apache.org/jira/browse/KAFKA-12223
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 2.7.0
> Reporter: Bruno Cadonna
> Priority: Minor
>
> Currently, for the recording of properties-based RocksDB metrics, we consider
> setups where some RocksDB state stores use a shared block cache and some
> other RocksDB state stores use dedicated block caches as an illegal state and
> we throw an \{{IllegalStateException}}. However, technically, it is possible
> to configure such a mixed setup through the RocksDB config setter and thus we
> should probably not consider it an illegal state. Allowing such a mixed setup
> would complicate the measurements of the block cache metrics.
