> Ameliorate compaction made by bulk-loading files
> ------------------------------------------------
>
> Key: HBASE-26249
> URL: https://issues.apache.org/jira/browse/HBASE-26249
> Project: HBase
> Issue Type: Improvement
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-2
>
>
> HBASE-25213 introduced to trigger compact after bulkload, but if a store
> needs compaction, each file loaded to this store will add a compaction runner
> of this store to the compaction queue. Then repeatedly compute for
> needCompaction and selectFiles for this store, and the compaction of the
> store may be continuous.
> We can mark the queued compaction runners for the stores, and avoid
> repeatedly adding same store compactions to the queue after bulk load files.
> This method can reduce the pressure during the period just after bulk loading
> and spread the pressure to other times by the periodic CompactionChecker.
> For the need of splitting mentioned before, after the completion of
> compaction, it will trigger split of the region if it needs. So we do not
> need to trigger split after bulk loading.
