If attempting to open a change stream against a collection on which change streams have not been enabled, an OperationFailure error will be raised. If this property is set to True, when this error is seen, the tap will execute an admin command to enable change streams and then retry the read operation. Note: this may incur new costs in AWS DocumentDB. |
