After Enabling Tableau Catalog, Disk Space Usage Increasing Tremendously

Published: 14 Mar 2020
Last Modified Date: 08 Jul 2022

Issue

After enabling Tableau Catalog, disk space usage increases tremendously. Huge csv files (postgresql-<day of week>.csv) are being accumulated in PostgreSQL database logs folder, which may cause running out of disk space.

Environment

Tableau Server 2020.1
Tableau Server 2019.4
Tableau Server 2019.3

Resolution

Upgrade to Tableau Server 2019.4.10, 2020.1.7, 2020.2.4

Cause

This behavior is related to a known issue with ID 1022313, which has been corrected in more recent versions of Tableau Server.

Additional Information

Manually deleting postgresql-<day of week>.csv does not affect Tableau Server processes and data.
postgresql-<day of week>.csv does not include indexed metadata. It is the log of PostgreSQL database for error reporting and logging. It can be useful for gathering statistics in high-load installations, but usually no need for keeping it.
