Multi-node | SurrealDB

Run SurrealDB against distributed storage for horizontally scalable, highly available clusters.

Multi-node SurrealDB requires shared distributed storage — a backend that every query node can reach with transactional consistency. A single RocksDB file on one server (or one Kubernetes pod) is not a multi-node cluster; it is the single-node, on-disk model.

For managed production clusters, see the Scale plan on SurrealDB Cloud. For self-hosted highly available setups on Kubernetes, see Amazon EKS, Google GKE, and Azure AKS.

Local development

The following starts a local distributed-storage playground for development, then connects SurrealDB to it.

curl -sSf https://tiup-mirrors.pingcap.com/install.sh | sh
tiup playground --tag surrealdb --mode tikv-slim --pd 1 --kv 1

Start SurrealDB against the playground endpoint:

surreal start tikv://127.0.0.1:2379

The default logging level for the database server is info. To control the logging verbosity, specify the --log argument. The following command starts the database with debug level logging, resulting in more logs being output to the terminal. If extra verbosity is not needed, specify a lower level or simply remove the flag, which will default to the info level.

surreal start --log debug tikv://127.0.0.1:2379

Configure your initial root-level user with --user and --pass. The root user is persisted in storage, so you do not need those flags on subsequent starts.

surreal start --user root --pass secret tikv://127.0.0.1:2379

Change the listen port with --bind:

surreal start --user root --pass secret --bind 0.0.0.0:8080 tikv://127.0.0.1:2379

After running the above command, you should see the SurrealDB server start up successfully.

surreal start --user root --pass secret --bind 0.0.0.0:8080 tikv://127.0.0.1:2379

Environment variables

Environment variables such as SURREAL_TIKV_REQUEST_TIMEOUT can be set to modify distributed-storage client behaviour. See distributed storage environment variables.
