Subject [jira] [Commented] (REEF-1413) Improve efficiency of DFSEvaluatorLogOverwriteWriter
Date Fri, 03 Jun 2016 18:31:59 GMT


Andrew Chung commented on REEF-1413:

Yes, that makes sense for the AppendWriter, but maybe it's a good idea to do some sort of
semantic compression in the AppendWriter as well at some point when the logs get too big.

> {{DFSEvaluatorLogOverwriteWriter}} currently reads from original EvalutorChangesLog before
overwriting it. This can become a problem when the job has been running for a long time. We
can make this more efficient by simply recording the Evaluators it expects in a log.
