Parallel Queries with PostgreSQL

This talk is an overview on Parallel Queries, introduced in the latest release of PostgreSQL.

This feature is still being developed, and new capabilities will be added in the next releases. Nevertheless, the current implementation is already rather useful, and we will show realistic examples running on PostgreSQL 10.

We will also describe the architecture of Parallel Queries, the new node types introduced, and how parallel aggregates work. This will lead to a discussion on which kinds of queries can benefit more from this feature.
