Lars Hofhansl commented on PHOENIX-5592:
----------------------------------------
May I ask why we need this? Expired rows should be removed via the normal
compaction process. If that does not work we might want reconsider this.
Requiring external M/R jobs for a feature like this is not a good idea, IMHO.
Is this is addition to removal with compactions?
> MapReduce job to asynchronously delete rows where the VIEW_TTL has expired.

> Find the entities from the system catalog which views have TTLs defined on
> them. Spawn an MR job, whose splitter will create a map task. The mapper
> issues “select count(1) from the entity and Inject TTL attributes and Delete
> Hint during Map task. Since the current Phoniex MR framework doesn't support
> this feature, PhoenixMultiViewReader, PhoenixMultiViewInputSplit,
> PhoenixMultiViewInputFormat, and a few MR related util classes need to
> implement.
