Will trace flag 8207 be supported with Azure SQL Database when enabling CDC? /cc MaraSteiu
Enables singleton updates for Transactional Replication and CDC. Updates to subscribers can be replicated as a DELETE and INSERT pair. This might not meet business rules, such as firing an UPDATE trigger. With trace flag 8207, an update to a unique column that affects only one row (a singleton update) is replicated as an UPDATE and not as a DELETE or INSERT pair. If the update affects a column on which a unique constraint exists, or if the update affects multiple rows, the update is still replicated as a DELETE or INSERT pair. For more information, see this https://www.betaarchive.com/wiki/index.php?title=Microsoft_KB_Archive/302341.
This flag is very useful when using CDC to generate change notification messages to downstream services. I believe it is not currently possible to set global trace flags on Azure SQL Database.
