Скачать или смотреть Following Select Statements Through Citus Internals | Citus Con: An Event for Postgres 2022

Talk by Onder Kalaci at Citus Con: An Event for Postgres. Abstract: Citus is a PostgreSQL extension that transforms Postgres into a distributed database. For some users, how this transformation happens is not obvious. In this talk, I'd like to walk you through Citus internals while a SELECT query is processed. In the end of the talk, you'd gain more insights on the internals of how the Citus query planner and adaptive executor work with the Postgres database.

Onder Kalaci is a Principal software engineer on the Postgres team at Microsoft. Prior to Microsoft, Onder joined Citus Data to scale out Postgres.
