bq. So moving local index writes to postBatchMutateIndispensably hook makes
very sense(After HBASE-15600 we don't need this at all).
I see HBASE-15600 is in 1.3 and up.
Does it make sense to make improvements on Phoenix master branch that take
advantage of such changes? Would it fine to say master aka Phoenix 5 is only
compatible with HBase 1.3 and up? If so I suggest taking all available steps to
improve the implementation of indexes.

Edit: In fact some are talking about branching for HBase 1.4 soon. If you like
we can organize changes in both layers to accomodate. For Phoenix 5.x and HBase
1.4.x.

> [~mujtabachohan] pointed out an "exponential" increase in update time in the
> size of the batch.
> Indeed when I look at the code in Indexer.java I see that for each call to
> postPut or postDelete we do insert the entire into the local index. (So for a
> batch of size 10000 we'd make 10000 index updates 10000 times)
