Data Replication

PostgreSQL Replication refers to the process of copying data from one PostgreSQL database server to another server.
A key idea in database administration is data replication, which gives essential systems high availability, fault tolerance, and scalability. Data replication is essential for assuring data durability, reducing downtime, and dispersing the workload over different servers in PostgreSQL, a powerful and feature-rich open-source relational database.

Data replication has a variety of applications:

  1. Online transactional processing (OLTP) performance: the transaction processing time and query time of an OLTP system can be improved by removing reporting query load.
  2. Fault Tolerance: The replica server can take over in the event that the master database server fails,
  3. Data Transfer
  4. Testing Systems in Parallel: Results on the same data from the old and new systems must be compared when moving an application from one DBMS to another to make sure the new system performs as intended.
