Jonathan Hsieh commented on HBASE-11861:
----------------------------------------
Two straw man suggestions.
1) Integrate the TTL cleaner as a Chore that the master runs periodically (once
every 24 hours by default?)
2) Explore ideas to enable a per mob hfile sweep (traverse back to natural
hbase row do some sort of bulk load with all the new pointers) so that we can
compact without using mr.
> Native MOB Compaction mechanisms.

> Key: HBASE-11861
> URL: https://issues.apache.org/jira/browse/HBASE-11861
> Project: HBase
> Issue Type: Sub-task
> Components: regionserver, Scanners
> Affects Versions: 2.0.0
> Reporter: Jonathan Hsieh
>
> Currenlty, the first cut of mob will have external processes to age off old
> mob data (the ttl cleaner), and to compact away deleted or over written data
> (the sweep tool).
> From an operational point of view, having two external tools, especially one
> that relies on MapReduce is undesirable. In this issue we'll tackle
> integrating these into hbase without requiring external processes.
