Feature compatibility
=====================

Server feature/commit scope interoperability
--------------------------------------------

Not all server features work with all commit scopes. This table shows
the ones that interoperate.

Notes
^^^^^

N/A : The Async column in the table represents PGD without a synchronous
commit scope in use. Lag Control isn’t a synchronous commit scope. It’s
a controlling commit scope and is therefore available with asynchronous
operations.

Attempting to use Group Commit and Transaction Streaming presents a
warning. The warning suggests that you disable transaction streaming,
and the transaction appears to take place. In the background, Group
Commit was disabled to allow the transaction to occur.

Commit scope/commit scope interoperability
------------------------------------------

Although you can’t mix commit scopes, you can :ref:`combine rules <Commit scope rules>`  with an
``AND`` operator. This table shows where commit scopes can be combined.

Notes
^^^^^

Each commit scope implicitly works with itself.
