Batch Mode

Often times, you don't apply a change to a single database. Instead, you need to apply a change to several databases. The most common case is you need to propogate a change from dev -> test -> staging -> prod, and each environment corresponds to a different database. Bytebase supports this case out of the box. In addition to that, Bytebase also offers a special batch mode to support:

• Partitioned databases and tables.
• Isolated tenant databases provisioned by multi-tenant service provider for each tenant.

Database Group

A database group is a collection of physical databases from one or more database instances that are considered as a single unit. To be grouped in the same database group, physical databases must meet the following criteria:

• They must belong to the same project.
• They must be in the same environment.
• They must conform to the rules specific to the database group.

To learn how to create database groups, you can visit Create a Database Group for details.

Table Group

A table group is a collection of physical tables from a single database group. Within a database group, you can create multiple table groups using configurable rules. A physical table can belong to one or more table groups.

Visit Create a Table Group to learn how to create a table group within a database group.

To apply a database change across multiple physical databases simultaneously, you can use database groupsand table groups. Head over to Change databases from database groups for details.

Tenant Database

Tenant databases are the homogeneous databases with identical schema. Each individual database corresponds to the combination of a tenant, location, and deployment environment.

Bytebase offers streamlined experience for tenant databases through Change databases from multiple tenants.
