Replication can provide high-availability horizontal scaling for high volumes of simultaneous read operations, along with reduced read latencies. It also allows for peer-to-peer replication between geographically distributed database servers. Version In a logical replication scheme, high-level write operations are streamed from a master database server into one or more replica database servers. In a physical replication scheme, binary write operations are instead streamed from master to replica, producing a byte-for-byte exact copy of the original content. In cases where you would like to target a particular subset of data, such as off-load reporting, patching, or upgrading, logical replication can offer speed and flexibility. By the end of the tutorial you will be able to replicate data from the master server to the replica using logical replication. There are several configuration settings you will need to modify to enable logical replication between your servers.
