[jira] [Created] (FLINK-10118) Queryable state MapState entry query
Elias Levy created FLINK-10118:
----------------------------------
Summary: Queryable state MapState entry query
Key: FLINK-10118
URL: https://issues.apache.org/jira/browse/FLINK-10118
Project: Flink
Issue Type: Improvement
Components: Queryable State
Affects Versions: 1.6.0
Reporter: Elias Levy
Queryable state allows querying of keyed MapState, but such a query returns all MapState entries for the given key. In some cases, such MapState many include substantial number of entries (in the millions), while the user may only be interested in one entry.
I propose we allow queries for MapState to provide one or more map entry keys, in addition to the state key, and to only return entries for the given map keys.
