![]() Data migration: You can leverage PostgreSQL replication for data migration either through a change of database server hardware or through system deployment.Here are a few key benefits of leveraging PostgreSQL replication: There are dedicated tools that allow automatic failover and automatic switching to the standby, cutting down on database downtime.īy setting up failover replication, you all but guarantee high availability by ensuring that standbys are available if the primary server ever collapses. Luckily, you don’t have to be dependent on PostgreSQL for failover. There are no built-in tools to monitor and scope server failures in PostgreSQL, so you’ll need to get creative. Note that the failover process can take some time to set up and initiate. As long as you’ve configured PostreSQL to manage your physical streaming replication, you - and your users - will be protected from downtime due to a primary server snafu. What Is Automatic Failover?įailover is a method for recovering data if the primary server gives out for any reason. The primary node can then apply these changes and broadcast them to secondary nodes. The PostgreSQL database follows a straightforward replication model, where all writes go to a primary node. ![]() The source database server is also known as the “primary” server, whereas the database server receiving the copied data is known as the “replica” server. PostgreSQL replication is defined as the process of copying data from a PostgreSQL database server to another server. What Is PostgreSQL Replication? PostgreSQL replication illustration (Image Source: EnterpriseDB) In this article, we’ll dive into the different strategies that can be implemented by backend developers for seamless PostgreSQL replication. It’s considered to be the best strategy for attaining high availability during disasters. Setting up replication between two databases offers fault tolerance against unexpected mishaps. ![]() You can also leverage the replicated database to process read-only SQL, allowing more processes to be run within the system. It’s an integral technology for any site or app running a database server. To protect the integrity of your site, it’s vital to build safeguards against the possibility of downtime or data loss.ĭata replication is an automated backup process in which your data is repeatedly copied from its main database to another, remote location for safekeeping. They can hit the unprepared at any time, leading to reduced productivity, accessibility, and product confidence. As any site owner will tell you, data loss and downtime, even in minimal doses, can be catastrophic.
