Apache CouchDB

Apache CouchDB at a glance

Apache CouchDB is a widely used open-source document database with a HTTP/JSON API and multi-master replication, common in offline-first and distributed applications. CouchDB ships regular releases plus coordinated security fixes; as a database with an HTTP interface, hardening and timely updates matter.

For admins the cardinal rule is exposure: CouchDB speaks HTTP and has been leaked through open, unauthenticated instances — never expose it to the internet without authentication and TLS, and bind it appropriately. It has had security advisories (including privilege-escalation classes), so apply security releases promptly. Updates within a line are usually routine; in a cluster, roll nodes carefully and back up first. Check replication and application compatibility across versions. After updating, verify that the API, databases and replication work. Its replication is powerful but means misconfiguration can propagate widely. Track the version and its support window; patchletter surfaces new CouchDB releases.
