-------------------------------------
Status: Open (was: Patch Available)
Asokan, apologies for the delay.
I'm very confused about this patch.
Can you please explain why you need ReduceInputMerger and why it has only some
of the interfaces in MergeManager?
How do you intend to use this for SyncSort?
Thanks.
