Subject Physical Operator Tag Change (SPLIT -> REPLICATE)
Date Wed, 28 Sep 2016 00:01:40 GMT
Hello All,

Regarding the index-only plan, I am going to introduce an operator named
SplitOperator that propagates each tuple to only one output branch.
Currently, ReplicateOperator propagates each tuple to all output branches.
And ReplicatePOperator uses the physical operator tag as SPLIT. I suggest
we change it to REPLICATE. Thus, SPLIT tag can be used for real Split
operator. Any thoughts?

Best,
Taewoo
