> Optimize mob compaction with _del files
> ---------------------------------------
>
> Key: HBASE-17172
> URL: https://issues.apache.org/jira/browse/HBASE-17172
> Project: HBase
> Issue Type: Improvement
> Components: mob
> Affects Versions: 2.0.0
> Reporter: huaxiang sun
> Assignee: huaxiang sun
> Attachments: HBASE-17172-master-001.patch,
> HBASE-17172.master.001.patch, HBASE-17172.master.002.patch
>
>
> Today, when there is a _del file in mobdir, with major mob compaction, every
> mob file will be recompacted, this causes lots of IO and slow down major mob
> compaction (may take months to finish). This needs to be improved. A few
> ideas are:
> 1) Do not compact all _del files into one, instead, compact them based on
> groups with startKey as the key. Then use firstKey/startKey to make each mob
> file to see if the _del file needs to be included for this partition.
> 2). Based on the timerange of the _del file, compaction for files after that
> timerange does not need to include the _del file as these are newer files.
