Stream and Task Replication: Changes for GA¶
This behavior change is in the 2023_03 bundle.
For the current status of the bundle, refer to Bundle History.
Stream and task replication is currently in preview and can be explicitly enabled for a database, replication or failover group, or an account.
In a future release, stream and task replication will be generally enabled and will change as follows:
Streams and tasks in a database are not replicated unless you have enabled the stream and task replication preview.
If you have not explicitly enabled stream and task replication, replication of a database with streams succeeds, but the streams are ignored (that is to say, they are not replicated to the target account).
Replication of databases that contain streams will fail in the following scenarios:
If the database that contains the stream and the database that contains the base object referenced by the stream:
Are separate databases or
Are in different replication or failover groups
If a database contains a stream that references an unsupported object. These include:
Tables or views in shared databases (i.e. databases shared from provider accounts to your account)
Tasks that have an initial version of the task set in the source account will be replicated to target accounts. For task replication scenarios, refer to Replication Scenarios.
To avoid replication failures for databases containing streams:
The replicated database must include both the stream and its base object or
The database that contains the stream and the database that contains the base object referenced by the stream must be included in the same replication or failover group.
