Hi All, I was reading about parallel queries in postgresql 10.
I came across the property max_parallel_workers_per_gather. It sets the maximum number of workers that can be started by a single Gather or Gather Merge node. I am not able to understand gather and gather merge node. What is the difference between max_parallel_workers_per_gather and max_parallel_processes. What is meant by gather node. Please let me know. Thanks, Krithika
