This section reports requests for worker processes and worker process memory. A parallel query may make multiple requests for worker processes. For example, a parallel query that requires a sort may make one request for accessing data and a second for parallel sort.
The “Requests Granted” and “Requests Denied” rows show how many requests were granted and how many requests were denied due to a lack of available worker processes at execution time.
To see the number of adjustments made to the number of worker processes, see “Parallel query usage”.
“Requests Terminated” reports the number of times a request was terminated by user action, such as pressing Ctrl-c, that cancelled the query.
