-------------------------------------
Summary: 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: Bug
Components: streams
Affects Versions: 2.7.0
Reporter: Bruno Cadonna
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.
