  - getAccessControl
```
default ConnectorAccessControl getAccessControl()
```
    Throws:
    
    UnsupportedOperationException - if this connector does not have an access control
  - commit
```
default ConnectorCommitHandle commit(ConnectorTransactionHandle transactionHandle)
```
    Commit the transaction. Will be called at most once and will not be called if rollback(ConnectorTransactionHandle) is called.
  - rollback
```
default void rollback(ConnectorTransactionHandle transactionHandle)
```
    Rollback the transaction. Will be called at most once and will not be called if commit(ConnectorTransactionHandle) is called. Note: calls to this method may race with calls to the ConnectorMetadata.
