### Is your feature request related to a problem or challenge? At the moment GroupedHashAggregateStream will spill state as a single batch, which is not optimal when merging as it loads whole file in memory as a single batch. ### Describe the solution you'd like I'd like to spit spill batch into smaller chunks with default batch size same as default batch size set in configuration property. ### Describe alternatives you've considered I have considered setting batch size to a fixed size or read from configuration property, but at the moment I did not do it as it would be bigger change. ### Additional context Relates to #7858 -- This is an automated message from the Apache Git Service.
