Scaling & Replicas

Scale replicas

zwrm postgres scale <name> <count>

Argument	Type	Description
`name`	string	Database name
`count`	int	Total instance count (primary + replicas)

A count of 1 means the primary only. A count of 3 means the primary plus 2 read replicas.

Add 2 read replicas:

zwrm postgres scale my-db 3

Scale back to primary only:

zwrm postgres scale my-db 1

View the available size presets:

zwrm postgres presets

Each preset defines the vCPU count, memory, and storage for the database VM. Choose a size when creating the database with --size:

zwrm postgres create my-db --size large

You can stop a database to free resources while keeping your data:

zwrm postgres stop my-db
zwrm postgres start my-db

The data volume is preserved across stop/start cycles.
