-----------------------------------

             Summary: Restore 1.12 SQL docs page on state retention
                 Key: FLINK-24016
                 URL: https://issues.apache.org/jira/browse/FLINK-24016
             Project: Flink
          Issue Type: Improvement
          Components: Documentation, Table SQL / API
    Affects Versions: 1.13.2, 1.14.0
            Reporter: Nico Kruber


{color:#1d1c1d}It seems that the whole {color}[section about state retention from the docs|https://ci.apache.org/projects/flink/flink-docs-release-1.12/dev/table/streaming/query_configuration.html#idle-state-retention-time]{color:#1d1c1d} in Flink 1.12 vanished with Flink 1.13. It was outdated with these min/max settings but instead of updating it, it was just removed and state retention/TTL is now safely hidden in [https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/table/config/#table-exec-state-ttl]{color}

{color:#1d1c1d}The discussion in the 1.12 docs is, however, superior since it explains a bit more why we need it and the types of queries that need it. I therefore propose to restore it somewhere in the docs.
