Lars Hofhansl commented on PHOENIX-3970:
----------------------------------------
bq. If index handler pool on RS1 is being used to write to data table, then the
index mutations originating from RS2 to RS1 could be blocked because all the
index handlers on RS1 are taken.
Oh no no, that's not what this patch is doing. [~samarthjain]. This patch is
just making sure that the read scan that ends up executing the index updates on
the remote indexes is also run by an index handler.
No data-table writes should be done with an index handler thread.
> Ensure that automatic partial index rebuilds are served from the index
> handler pool
