--------------------------------
Summary: Introduce latency tracking state
Key: FLINK-21736
URL: https://issues.apache.org/jira/browse/FLINK-21736
Project: Flink
Issue Type: New Feature
Components: Runtime / State Backends
Reporter: Yun Tang
Assignee: Yun Tang
Fix For: 1.13.0
This ticket is extended from FLINK-16444 which wants to track latency of
RocksDB options. However previous ticket has two problems:
# Cannot apply to heap based state backend and other user customized state
backend.
# User need background knowledge to know what RocksDB operation corresponding
to what state operation, e.g RocksDB adopts {{merge}} to act as listState#add.
Thus, I prefer to introduce latency tracking state wrapper to detect the access
latency. And to not impact the original state access, I would still use sample
interval as previous FLINK-16444 did.
