The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.6/static/parallel-query.html Description:
Hi, maybe i overlooked something, but i have hard time to unterstand, why max_parallel_workers_per_gather was not fully utilised in some cases. After reading the source code, I realized that there is a setting at table level: parallel_workers (https://www.postgresql.org/docs/9.6/static/sql-createtable.html#SQL-CREATETABLE-STORAGE-PARAMETERS) I think it would help, if this setting is mentioned in the chapter for parallel query (https://www.postgresql.org/docs/9.6/static/parallel-query.html) Perhaps this page would be a good place: https://www.postgresql.org/docs/9.6/static/when-can-parallel-query-be-used.html Regards, Marc-Olaf -- Sent via pgsql-docs mailing list (pgsql-docs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-docs
