Unlocking the Postgres Lock Manager

Date: 2018-02-02
Time: 11:30–12:20
Room: Hotel
Level: Intermediate

Locking is critical for providing high concurrency for any database — you cannot fully utilize your hardware if locking is throttling its use. This talk explores all aspects of locking in Postgres by showing queries and their locks; covered lock types include row, table, shared, exclusive, and advisory lock types. The high concurrency provided by Multiversion Concurrency Control (MVCC) is also covered.
