Vinoth Chandar resolved HUDI-1707.
----------------------------------
> Improve Logging subsystem
> -------------------------
>
> Key: HUDI-1707
> URL: https://issues.apache.org/jira/browse/HUDI-1707
> Project: Apache Hudi
> Issue Type: Improvement
> Components: Code Cleanup
> Reporter: Volodymyr Burenin
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.11.0
>
>
> Currently Hudi has a relatively verbose logging on info level that is not
> particularly useful. Like latency measurements of file system views, print
> out of commit timelines, etc that could be super large, etc.
> Additionally to that, the logging subsystem is suboptimal as it formats all
> messages before they are being passed into the logger, so it doesn't matter
> if logger will or will not print out a log message a lot of work is still
> being done anyway.
> Would be also nice to add more messages on info level to determine at which
> phase Hudi is: ideally, the info level should be limited to the point that
> just looking into the logs should be clear enough at which phase Hudi is and
> what it is doing without being too verbose.
> TBD: Add more thoughts on logging subsystem
