I was looking forward to upgrading to 0.19 because I read about druid.segmentCache.lazyLoadOnStart. I have roughly 140,000 segments for some reason (currently on a single node). It takes an hour or two to start the historical service. I set the druid.segmentCache.lazyLoadOnStart to true and fired it up. It’s still taking forever. I see a flood of messages like:
2020-08-22T10:23:57,694 INFO [main] org.apache.druid.server.coordination.SegmentLoadDropHandler - Loading segment cache file [87629/137779][var/druid/segment-cache/info_dir/Event_1_2020-06-27T19:00:00.000Z_2020-06-27T20:00:00.000Z_2020-06-27T18:53:12.884Z_118].
Is this expected? Or am I missing something here?
