Hi Team, I'm using fields grouping for a bolt to maintain field-based ordering, but I'm facing data skewness among the bolt's executors. I have 96 executors, and I'm sending data with 500 distinct fields used in the fields grouping. While reviewing the Storm UI, I noticed that a few executors are underutilized while others are overutilized.
This seems to be a hashing problem i guess. Can anyone suggest a better hashing technique or approach to resolve this issue? Thanks in advance for your help.
