SQL 2025 Fabric Mirroring
Hi baloocc1,
I would be careful with this configuration.
For SQL Server 2025 Fabric Mirroring, Microsoft documentation says that Replication and CDC are not supported on the mirrored database.
https://learn.microsoft.com/en-us/fabric/mirroring/sql-server-limitations
So even if the setup appears to work, I would treat it as unsupported unless Microsoft confirms otherwise.
The 30-second latency may be normal because Fabric Mirroring is not always instant, but the main concern is the use of Replication with Fabric Mirroring.
I would test the same scenario on a clean SQL Server 2025 database without Replication or CDC and compare the behavior.
In short: good proof of concept, but I would not use this design in production without confirmation from Microsoft Support.
