I wonder how many threads run, for example, while PrimProc is running. In addition, could you let me know how I can limit the number of threads if it's possible? Thank you! |

Please review: https://mariadb.com/kb/en/mariadb/mariadb-columnstore-performance-related-configuration-settings/ This covers the main tuning parameters. These are not necessarily directly correlated with the number of threads utilized. In general columnstore will try to create as many threads as possible to reduce processing time of the primitive tasks. Can i ask why you want to limit the the number of threads? Generally columnstore is designed to consume the resources available to it. You could artifically do this using virtual machines if you are trying to share a very large physical server. |
