weight: 40
---
As of v1.0.0, K3s is previewing support for running a highly available control plane without the need for an external database. This means there is no need to manage an external etcd or SQL datastore in order to run a reliable production-grade setup. While this feature is currently experimental, we expect it to be the primary architecture for running HA K3s clusters in the future.
As of v1.0.0, K3s is previewing support for running a highly available control plane without the need for an external database. This means there is no need to manage an external etcd or SQL datastore in order to run a reliable production-grade setup.
This architecture is achieved by embedding a dqlite database within the K3s server process. DQLite is short for "distributed SQLite." According to https://dqlite.io, it is "*a fast, embedded, persistent SQL database with Raft consensus that is perfect for fault-tolerant IoT and Edge devices.*" This makes it a natural fit for K3s.
