Parallel Query In PostgreSQL
Robert has been involved in the PostgreSQL project since 2008, first as a patch reviewer and committer and a later as a major developer. Prior to that, he was a PostgreSQL application developer for nearly ten years. Features he has worked on include parallelism (9.4-9.6), the replacement of System V shared memory with anonymous shared memory (for 9.3), read and write scalability improvements (for 9.2), index-only scans (with Heikki Linnakangas and Ibrar Ahmed, for 9.2), unlogged tables (for 9.1), and left join removal (for 9.0). He works at EnterpriseDB as Chief Database Architect for the Database Server.
I and others have been working on bringing parallel query for PostgreSQL for several years now, but PostgreSQL 9.6 is the first release expected to include a user-visible feature. And it's pretty cool. In this talk, I'll give an overview of the development of this feature, where we are now, and what the future might hold. I will discuss the overall architecture of parallelism in PostgreSQL, give examples of queries that can be accelerated by the features expected to be in PostgreSQL 9.6, and talk about what's not done yet.
