Subject Partitioner is spending around 2 to 4 minutes while pushing data to next operator
Date Thu, 22 Jun 2017 09:58:31 GMT
I have a execution flow (Streaming Job) with parallelism 1.

 source -> map -> partitioner -> flatmap -> sink 

Since adding partitioner will start new thread but partitioner is spending
average of 2 to 4 minutes while moving data from map to flat map .

For more details about this  : 

In some link here :

they have mentioned that the

 PipelinedSubpartition is a pipelined implementation to support streaming
data exchange. The SpillableSubpartition is a blocking implementation to
support batch data exchange.

I am not sure how would i use these or reduce latency from map ->
partitioner -> flatmap .
