-------------------------------------
Summary: Reuse cache from previous history server run
Key: FLINK-14166
URL: https://issues.apache.org/jira/browse/FLINK-14166
Project: Flink
Issue Type: Improvement
Reporter: David Moravek
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.
