1. I'm not sure how you would determine the appropriate amount of memory without just trying it out. Ballista by no means loads all 50GB into memory at the same time - it breaks it up into smaller RecordBatches for processing. 2. Ballista will run your query on as many executors as it can successfully parallelize (likely as many as you give it, depending on the query). -- This is an automated message from the Apache Git Service.
