Hello. I am trying to benchmark a simple Trident topology: IBatch Custom Spout -> Bolt. Every time I am starting topology I have the same issue - *a delay between the first and the second batch*.
Legend of the picture: blue - timestamp of emitting tuple, yellow and green - timestamps of processing steps in Bolt, magenta - timestamp of ack function in Spout. So in this case every tuple is succesfully processed, but acknowledgment comes after *30 seconds*. Do you have any ideas of what is happening?
