> Limit operator currently invokes kill() when it reaches the desired limit of
> records. Current semantic of kill() does not stop upstream operators if they
> are across exchanges. So its the responsibility of the operator to drain out
> all the record batches and clear the memory, otherwise we will hit memory
> leaks.
