Vacuuming is a key feature of PostgreSQL databases to keep databases healthy and optimized. When enabled, autovacuum conserves space by removing obsolete disk usage and optimizes database performance by speeding up sequential scans, among many other benefits.
As part of the ongoing PostgreSQL Webinar Series, 2ndQuadrant hosted a webinar on Postgres Vacuuming Through Pictures, which covered key concepts of Postgres Vacuum and Autovacuum, and provided a demonstration on how tuning vacuum properly makes a difference in database performance. The webinar was presented by Tom Kincaid, GM North America at 2ndQuadrant.
You can now watch the full webinar, first held on 24 July, 2019.
