View some of the frequently asked questions regarding SurrealDB, SurrealQL, and SurrealKV. Questions which are frequently asked across our GitHub, Discord and other social platforms will be added here from time-to-time. SurrealDB is currently in version v2.1.4.
Once features are released, we document them in our release notes and on our features page, which is a great place to understand capabilities.
You can also check some of our new features for v2.1.4:
SurrealDB can be scaled vertically on a single-node, by adding more compute power and memory to a server instance. SurrealDB can also be scaled horizontally by sitting infront of, and connecting to a TiKV to store data. TiKV is a highly scalable, low latency, and easy to use key-value datastore. TiKV supports raw and transaction-based querying with ACID compliance, and support for multiple concurrent readers and writers. The design of TiKV is inspired by distributed systems from Google, such as BigTable, Spanner, and Percolator, and some of the latest achievements in academia in recent years, such as the Raft consensus algorithm. , or FoundationDB distributed cluster. When running in this mode, SurrealDB offloads the storage to the key-value store, operating as an advanced query engine layer. It is then possible to increase the number of SurrealDB nodes as required, in order to handle the query and transaction processing requirements.
Source code for SurrealDB is variously licensed under a number of different licenses. A copy of each license can be found in each repository on GitHub. For more information on the licenses view the license details page.

You can use and scale SurrealDB to any number of nodes, and can run it as a server or embed it in to your applications (whether you ship those applications to customers or run them as a service). You can even run it as a service internally, to your employees, contractors, and subsidiary companies. The only thing that you are not able to do is offer a commercial, hosted version of SurrealDB as a service (a database-as-a-service) without buying a license.
