> how many rows are there in the 1 hour interval ? The num of rows is 180 million in the 1 hour interval. >For you task configuration, up to 10g direct memory is available for JVM, but only (2 numMergeBuffers +2 numThreads +1)*256MiB = 1280MiB is configured for Druid to use. The number of CPU of physical machine is 56, and the maximum number of peon is 30 in the middle manager. Does it mean that the numThreads per peon cannot exceed 2? if direct memory is 5g, how to balance numMergeBuffers and sizeBytes？ -- This is an automated message from the Apache Git Service.
