What Is a Multi-primary Instance?

A multi-primary instance can contain 2 to 63 read/write nodes, with no read replicas, enabling write many read many.

In a multi-primary instance, read/write nodes manage the metadata of the instance in a unified manner by sharing metadata. You can access the entire TaurusDB instance through a proxy address. The proxy instance automatically forwards your SQL commands to the correct read/write nodes.

Compared with a single-primary instance, a multi-primary instance allows for concurrent writes to different databases or tables on different nodes. Data can be concurrently written to up to 63 nodes, greatly improving the concurrent read/write capability.
