Enis Soztutar commented on PHOENIX-2428:
----------------------------------------
If an RS fails in between, I don't think there is a reliable way to detect this
and re-populate the index. The flush() will still succeed, but there is no
guarantee that you did not lose any data even if flush succeeds.
> Disable writing to WAL on initial index population

> We should not be writing the WAL when we initially populate an index. Not
> only is this obviously more efficient, but it also will prevent the writes
> from being replicated both of which are good.
