I don't see any in-balance. The value of "Executed" is 440/460 for each bolt. Thus each bolt processed about the same number of tuples.
Shuffle grouping does a round robin distribution and balances the number of tuples sent to each receiver. I you refer to the values "capactiy", "execute latency", or "process latency", shuffle grouping cannot balance those. Furthermore, Storm does not give any support to balance them. You would need to implement a "CustomStreamGrouping" or use direct-grouping to take care of load balancing with regard to those metrics. -Matthias On 06/23/2015 11:42 AM, bhargav sarvepalli wrote: > > > I'm leading a spout with 30 executors into this bolt which has 90 > executors.
