Hi All,

after increment of parallelism in bolts also spout is failing ? how can I
know how much time my bolts are taking to complete the tuple processing.I'm
using kafka spout with 10 partitions so I kept my
topology.max.spout.pending as 10 .do I need to increase the value more than
that?if yes to extent i can increase the  number ? as a stupid play i kept
the value 100 to 1 partition kafka it give me metrics error.



*Best regards,*
