Guozhang Wang created KAFKA-3183: ------------------------------------ Summary: Add metrics for persistent store caching layer Key: KAFKA-3183 URL: https://issues.apache.org/jira/browse/KAFKA-3183 Project: Kafka Issue Type: Sub-task Reporter: Guozhang Wang
We need to add the metrics collection such as cache hits / misses, cache size, dirty key size, etc for the RocksDBStore. However this may need to refactor the RocksDBStore a little bit since currently caching is not exposed to the MeteredKeyValueStore, and it uses an LRUCacheStore as the cache that does not keep the dirty key set. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
