Lars Hofhansl commented on PHOENIX-1609:
----------------------------------------
I'd say that DEFERRED implies that Phoenix will eventually - but automatically
- do it.
ASYNC means there's another process outside of Phoenix that it triggered
manually (from the viewpoint of Phoenix).
Maybe this is splitting hair... Either words imply that it won't happen
immediately.

> Often, we need to create new indexes on master tables way after the data
> exists on the master tables. It would be good to have a simple MR job given
> by the phoenix code that users can call to have indexes in sync with the
> master table.
> Users can invoke the MR job using the following command
> hadoop jar org.apache.phoenix.mapreduce.Index -st MASTER_TABLE -tt
> INDEX_TABLE -columns a,b,c
> Is this ideal?
