The data I am removing from cache is colocated on the same node. So I think
exchange will happen only for updating the backup copies. Please correct me
if I am wrong.
I believe that remove all operation first acquires the lock on all input
keys and then removes the data. If I go for single remove, will it not
acquire lock per key per remove operation. Will it not slow down?
Will try your suggestions.
