+            Only used when tap is run in log-based replication mode. This setting specifies how the tap creates a

+            in MongoDB 3.6 when the ChangeStream API was introduced. The `start_after` setting (see
+            https://www.mongodb.com/docs/manual/changeStreams/#startafter-for-change-streams) requires MongoDB
+            version 4.2 or greater. You may switch back and forth between `resume_after` and `start_after`
+            settings (provided the MongoDB version is at least 4.2) freely. If the value provided to this setting
+            is not compatible with the MongoDB version in use, this setting defaults to `resume_after`.
