MySQL | PostgreSQL | PostgreSQL to AlloyDB

Overview

In this page, you learn how to use the Database Migration Service API to manage connection profiles for a PostgreSQL source database and a AlloyDB destination.

There are two ways that you can use the Database Migration Service API. You can make REST API calls or you can use the Google Cloud CLI (CLI).

All data stored within Google Cloud is encrypted at rest using the same hardened key management systems that we use for our own encrypted data. These key-management systems provide strict key access controls and auditing, and encrypt user data at rest using AES-256 encryption standards. No setup, configuration, or management is required. Google Cloud's default encryption at rest is the best choice for users who don't have specific requirements related to compliance or locality of cryptographic material.

pageSize: Use this filter to specify the maximum number of connection profiles that Database Migration Service retrieves and displays on a page. For example, by setting pageSize=10, Database Migration Service will return up to 10 connection profiles for a page.

If there are more than 10 connection profiles, then they appear on other pages. At the end of each page, a nextPageToken parameter and unique identifier appear. Use the identifier to retrieve the listing of the connection profiles for the following page.

Delete a connection profile

Important: You can delete a connection profile only if there are no active migration jobs associated with the profile. If a connection profile has active migration jobs, then promote or delete the jobs.

To see whether a connection profile has any active migration jobs associated with it, run the following command:

GET https://datamigration.googleapis.com/v1/projects/project-id/locations/region/migrationJobs?filter=state:STATE_NAME OR state:STATE_NAME AND source:projects/project-id/locations/region/connectionProfiles/connection-profile-id

For example:

GET https://datamigration.googleapis.com/v1/projects/myproject/locations/myregion/migrationJobs?filter=state:RUNNING OR state:FAILED AND source:projects/myproject/locations/myregion/connectionProfiles/postgresql-to-alloydb-src1

The various states (statuses) of the migration job are:

NOT STARTED: The migration job is created, but it hasn't been started.
STARTING: The migration job is in the process of being started.
RUNNING: The migration job is running and can be used to migrate data from the source database to the destination database.
STOPPING: The migration job is in the process of being stopped.
STOPPED: The migration job is paused, and is no longer migrating data to the destination database.
RESUMING: The paused migration job is running.
FAILED: A problem occurred while the migration job was running.
RESTARTING: Database Migration Service takes a new snapshot of the source database, loads the initial dump into the destination database, and processes ongoing changes of data from the source database to the destination database.

If a user has a migration job in any of these statuses, and if the user attempts to delete the connection profile, then it will fail.

REST

Before using any of the request data, make the following replacements:

project-id: The project ID
region: The project region
connection-profile-id: The connection profile ID

HTTP method and URL:
