[jira] [Created] (KAFKA-4304) Extend Interactive Queries for return
latest update timestamp per key
Matthias J. Sax created KAFKA-4304:
--------------------------------------
Summary: Extend Interactive Queries for return latest update timestamp per key
Key: KAFKA-4304
URL: https://issues.apache.org/jira/browse/KAFKA-4304
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Matthias J. Sax
Assignee: Guozhang Wang
Priority: Minor
Currently, when querying state store, it is not clear when the key was updated last. The ides of this JIRA is to make the latest update timestamp for each key-value-pair of the state store accessible.
For example, this might be useful to
* check if a value was update but did not changed (just compare the update TS)
* if you want to consider only recently updated keys
