Summary: Create a compaction strategy for aging off data (was: use case
for future configurability of major compactions)
> 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
> Fix For: 1.7.0
>
>
> 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.
> Augment the configurable compaction strategy to support multiple output
> files, and saving/using extra metadata in each file.
