Schedule - FOSDEM PGDay 2016

Explaining the Postgres Query Optimizer

Date: 2016-01-31
Time: 14:00–14:50
Room: H.1309 (Van Rijn)
Level: Intermediate

The optimizer is the "brain" of the database, interpreting SQL queries and determining the fastest method of execution. This talk uses the explain command to show how the optimizer interprets queries and determines optimal execution. The talk will assist developers and administrators in understanding how Postgres optimally executes their queries and what steps they can take to understand and perhaps improve its behavior.
