           This will provide more accurate metrics for when sweep is doing something.  Sweeping run through the sweep endpoint will now also contribute to these metrics, before it didn't update any metrics which again distorted the view of what work sweep was doing on the DB.

-         - Size of the transaction cache is now configurable. It is not anticipated end users will need to touch this;
-           it is more likely that this will be configured via per-service overrides for the services for whom the
-           current cache size is inadequate.
-           This is a small API change for users manually constructing a TransactionManager, which now requires a
-           transaction cache size parameter. Please add it from the AtlasDbConfig, or instead of manually creating
-           a TransactionManager, utilize the helpers in TransactionManagers to have this done for you.

-         - Simplify and annotate the constructors for ``SerializableTransactionManager``. This should make the code of that class more maintainable.
-           If you used one of the deleted or deprecated constructors, use the static ``create`` method.
