Subject Enumerable groupBy() take advantage of input collation?
Date Thu, 20 Aug 2015 09:35:19 GMT
I encountered Out Of Mem exception when a huge result set is passed into
EnumerableAggregate and get aggregated in memory. I'm thinking if the input
is sorted by the group-by key, then the groupBy() don't have to hold all
data in memory any more.

So does the Enumerable groupBy() take advantage of input collation
currently?  Should I open a JIRA for it?


Cheers
Yang
