For optimum performance, a PostgreSQL database depends on the operating system parameters being defined correctly. Poorly configured OS kernel parameters can cause degradation in database server performance. This results in improved performance. SHMMAX / SHMALL.

Implementing table-level encryption may require additional resources and impact performance, so carefully evaluating the trade-offs between security and performance is essential. This key is usually stored in a secure location, such as a hardware security module (HSM). Encryption available in databases.

Reference tables can be replicated to all nodes for joins and foreign keys from distributed tables and for maximum read performance. Depending on the configuration, one can tune a hardware RAID for either performance or redundancy. The same can be said for Citus data sharding. citus_columnar | 11.1-1 1 citus | 11.1-1
