Validating EDB Postgres Distributed Continuous High Availability and Consistency for Active/Active Architectures (Part 1)

EDB Postgres Distributed (PGD) provides best-in-class high availability required for always-on, enterprise-grade Postgres database application performance across fully managed or self-managed deployments in any cloud. With EDB’s Postgres technology supporting robust, globally distributed applications that process thousands of transactions per second, customers regard EDB Postgres Distributed as their go-to for delivering up to 99.999% guaranteed uptime and improving the performance of data replication by up to 5X.

As part of internal activities leading up to our latest EDB Postgres Distributed release, our  Engineering team focused on how to deliver more robust releases that enhance customer confidence in PGD. Setting correct expectations for customers prompted us to enhance our internal testing processes in efforts influenced by the Jepsen database testing framework.

In the Jepsen framework, a Jepsen control node has the Jepsen libraries, together with plugins for PGD and tests. This talks to the PGD cluster as shown below.
