-----------------------------
Component/s: table-service
> Support LogFileModTimeBasedCompactionStrategy
> ---------------------------------------------
>
> Key: HUDI-4313
> URL: https://issues.apache.org/jira/browse/HUDI-4313
> Project: Apache Hudi
> Issue Type: Improvement
> Components: compaction, table-service
> Reporter: sivabalan narayanan
> Priority: Major
>
> we need to support a new compaction strategy called
> LogFileModTimeBasedCompactionStrategy.
> Using this strategy, we want to choose the file slice whose's earliest log
> file mod time for compaction.
> This will be similar to LogFileSizeBasedCompactionStrategy, just that instead
> of comparing total log files size for a given file slice, we will use
> earliest mod time for a given file slice.
> The goal is to compact some part of the whole change set (say, 20%) in one
> batch.
> Compaction plan for a next batch should include incomplete operations from
> the previous plans.
> Operations should be processed in order of earliest log file modification
> time.
