![]() We sill stick with the default for the master username as that is postgres usually anyway: The latest version as of today is 12.2, we want to go for production and we need to provide a name: In our case we want to go for PostgreSQL: This is usually what you want when you want a production deployment in AWS.Īs usual, with the AWS console, creating a new database is quite easy: In this post we’ll use these two building blocks to bring up a high available PostgreSQL instance using a master instance in one, and a replica in another availability zone. If writes haven't been stopped, or if writes are resumed before the status update, then the process fails and returns an error describing the cause of the failure.In the last tow posts we had a look at DB Parameter Groups and Subnet Groups as these need to be ready when you want to deploy a RDS PostgreSQL instance on AWS. To resume writing to the source database.ĭatabase Migration Service keeps trying to take the initial dump for approximately 20 minutes. Database Migration Service identifies that the writing stopped, and the status changes to Running | Preparing the dump.Īfter the status changes to Running | Full dump in progress, it's safe Writing should be stopped to the source database. The status changes can be tracked in the API, Console orĪfter the status changes to Starting | Waiting for source writes to stop, Indication of when to stop and resume writes is in the status and substatus of You can useĪ script to verify that all writing to the source database is stopped. Instead of stopping writes by migrating from a read replica in AWS, you can stop writes directly on the source database. You can stop writes either by migrating from a read replica or by stopping writes directly on the source database.Ĭreate a read replica in Amazon Web Services (AWS).Ĭonfigure the Database Migration Service source connection profile with the connectivity information of the AWS read replica.Īfter the status of the migration job changes to Starting | Waiting for source writes to stop, disable replication between the AWS primary and its read replica for approximately 20 seconds.Īfter the status of the migration job changes to Running | Full dump in progress, re-enable replication to the read replica in AWS. To take the initial full dump, both for MySQL RDS and for sources with no SUPERUSER privilege, writes should be stopped at the source for approximately 20 seconds.
