Feed: MariaDB Knowledge Base Article Feed. Author: . This guide will cover: The load balancing and high availability concepts in Mariadb Connector/J for version before 3.0 The different options. Failover and high availability were introduced in 1.2.0.

Feed: Planet PostgreSQL. What does High Availability actually mean when we’re discussing Postgres clusters? Sure, we can set an RPO, RTO, SLA, and other 3-letter acronyms regarding expectations and deliverables, but what are we trying to achieve? Fast failover? No lost transactions? Both?

How do all of our various replication configurables affect this?Let’s see if we can come up with a definition of High Availability that’s suitable to a Postgres context. This may seem a trivial exercise at first, but there’s a method to our madness. Starting from ... Read More
