TiDB

TiDB is an open-source distributed SQL database that remains MySQL compatible while scaling horizontally.

Kubernetes Deployment

I use TiDB Operator on Kubernetes:

TiDB Operator manages TiDB clusters on Kubernetes and automates tasks related to operating a TiDB cluster.

• Safely scaling the TiDB cluster
• Rolling update of the TiDB cluster
• Multi-tenant support
• Automatic failover
