Subject [GitHub] flink issue #4445: [FLINK-7310][core] always use the HybridMemorySegment
Date Tue, 01 Aug 2017 13:13:03 GMT
Github user StephanEwen commented on the issue:

    https://github.com/apache/flink/pull/4445
  
    These changes look good to me!
    
    There is in fact a potential performance impact of this change. It would be cool to get
an understanding of the potential performance impact of only using the HybridMemorySegment
now.
    We could run something like a Hash Join Performance test with key/value pairs of String
keys (which are the most performance sensitive to serialize / deserialize with individual
byte operations) and see if this has a measurable impact there.
