>
> {{IndexWhereTaskDispatcher}} is used when
> {{hive.optimize.index.filter=true}}. It lists all indices for the table and
> depending on the query complexity, this ends up being in the hotpath. For
> e.g, Q14 explain plan takes 180-200 seconds and this index querying multiple
> times for same tables take up 30-40 seconds. This function was invoked around
> 24000 times for same set of tables.
