> 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.
