Database

Zilliz Cloud introduces a database layer in between the clusters and collections, providing a more efficient way to manage and organize your data while supporting multi-tenancy.

What is a database​

In Zilliz Cloud, a database serves as a logical unit for organizing and managing data. To enhance data security and achieve multi-tenancy, you can create multiple databases to logically isolate data for different applications or tenants. For example, you create a database to store the data of user A and another database for user B.

The resources are structured in the following hierarchical order in Zilliz Cloud.

It can be noted that the concept of database is only available to Dedicated clusters. Serverless and Free clusters do not have databases.

Prerequisites​

You need to have Organization Owner or Project Admin access to manage databases.

Create database​

Databases can only be created in Dedicated clusters. Upon the creation of a cluster, a default database will be created.

You can create up to 1,024 databases in a Dedicated cluster.

You can also move created collections from one database to another. For more details, refer to Manage Collections (Console).

Drop database​

Default databases cannot be dropped.

Before dropping a database, you need to drop all collections in the database first.
