> Reuse cache from previous history server run
> --------------------------------------------

> Key: FLINK-14166
> URL: https://issues.apache.org/jira/browse/FLINK-14166
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Web Frontend
> Reporter: David Morávek
> Priority: Minor
> Labels: stale-minor
>
> Currently history server is not able to reuse cache from previous run, even
> when `historyserver.web.tmpdir` is set. It could simply "warm up" cached job
> ids set, from previously parsed jobs.
> https://github.com/apache/flink/blob/master/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/history/HistoryServerArchiveFetcher.java#L129
> This should be configurable, so it does not break backward compatibility.
