Chain’s enterprise blockchain networks use Postgres for storage. We rely on Postgres’s replication features to ensure that clients can always access their assets and create transactions, and wrote a service that manages Postgres replicas. This service was heavily inspired by Joyent’s Manatee project, but uses different technology; namely, Go and etcd instead of Node and Zookeeper. In this talk, we’ll cover how we use etcd to coordinate replicas in our high-availability management system. We’ll talk about how we configured both etcd and Postgres, walk through the high-level design as well as some code, demonstrate failover, and show how blockchain services communicate with this system.
