LinuxFest Northwest 2019: Your Herd of Elephants: PostgreSQL Replication
Presented by Christophe Pettus
PostgreSQL has added in-core logical replication, and now the field of replication options in PostgreSQL has gotten wide: Streaming replication, warm standby, logical replication… We'll discuss what the options are, their limitations and pitfalls, and what the best use-case for each one is. We'll show what it takes to set each one up, monitor it, and get it working again on failures.
We'll cover:
-The history of replication in PostgreSQL.
-WAL shipping
-Streaming replication
-Trigger-based replication
-Logical decoding
-And some exotic animals.
