> Eliminate MOB renames when SFT is enabled
> -----------------------------------------
>
> Key: HBASE-26969
> URL: https://issues.apache.org/jira/browse/HBASE-26969
> Project: HBase
> Issue Type: Sub-task
> Components: mob
> Affects Versions: 2.5.0, 3.0.0-alpha-3
> Reporter: Szabolcs Bukros
> Assignee: Szabolcs Bukros
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-4
>
>
> MOB file compaction and flush still relies on renames even when SFT is
> enabled.
> My proposed changes are:
> * when requireWritingToTmpDirFirst is false during mob flush/compact instead
> of using the temp writer we should create a different writer using a
> {color:#000000}StoreFileWriterCreationTracker that writes directly to the mob
> store folder{color}
> * {color:#000000}these StoreFileWriterCreationTracker should be stored in
> the MobStore. This would requires us to extend MobStore with a createWriter
> and a finalizeWriter method to handle this{color}
> * {color:#000000}refactor {color}MobFileCleanerChore to run on the RS
> instead on Master to allow access to the
> {color:#000000}StoreFileWriterCreationTracker{color}s to make sure the
> currently written files are not cleaned up
