4.2 Using Logical Replication
Last updated
What is 4.2 Using Logical Replication?
Logical replication is an asynchronous feature that allows data modification to be transferred from a source (publisher) to a target system (subscriber) across different PostgreSQL database versions. It provides more granular control over the data copied and is useful during an upgrade.
Advantages of Logical Replication
- It allows you to replicate only specific tables, rather than the entire database.
- You can create replicas with different database schemas by using a transformation layer between publisher and subscriber.
- It allows you to perform a live upgrade, avoiding the downtime of your database.
