Subject Does using Custom Partitioner before calling reduceByKey improve performance?
Date Tue, 27 Oct 2015 20:20:59 GMT
Hi,

We currently use reduceByKey to reduce by a particular metric name in our
Streaming/Batch job. It seems to be doing a lot of shuffles and it has
impact on performance. Does using a custompartitioner before calling
reduceByKey improve performance?


Thanks,
Swetha
