HeartSaVioR edited a comment on issue #26821: [SPARK-20656][CORE]Support Incremental parsing of event logs in SHS URL: https://github.com/apache/spark/pull/26821#issuecomment-564422644 @shahidki31 No I didn't intend to persuade you to close this. I'd just wanted to make sure we get a clear picture of full implementation before dealing with each part, but it's OK for me if you'd like to deal with current solution as I think I can deal with extending the solution with snapshotting. I can take a look with current solution, but you still need to persuade at least one committer to push this forward. Btw, we'd be better to clarify the performance test in details. It should include at least... * size of event log file for initial load * elapsed time for initial load * count/size of events for addition (mostly about size) * elapsed time for loading additional events For me, your statement in PR description sounds to me as skipping (via read and drop) 2G takes around 2 secs which is still not ideal (as we know how to do it better), though I agree that's still a huge improvement.
