> Create a compaction strategy for aging off data
> -----------------------------------------------
>
> Key: ACCUMULO-1802
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1802
> Project: Accumulo
> Issue Type: New Feature
> Components: tserver
> Reporter: Eric Newton
> Priority: Trivial
>
> The default compaction strategy has a tendency to put the oldest data in the
> largest files. This leads to a lot of work when it is time to age off data.
> One could imaging a compaction strategy that would split data into separate
> files based on the timestamp. Additionally, if the min/max timestamps for a
> file were known, old data could be aged off by deleting whole files.
> To accomplish this, will need to augment the configurable compaction strategy
> to support multiple output files, and saving/using extra metadata in each
> file.
