CursorAwareWriteTransaction
Transactions can only be cancelled if it was not yet submited.
Invoking cancel() on failed or already canceled will have no effect, and transaction is considered cancelled.
Invoking cancel() on finished transaction (future returned by CursorAwareWriteTransaction.submit()
already
successfully completed) will always fail (return false).

public com.google.common.util.concurrent.CheckedFuture<Void,TransactionCommitFailedException> submit()
CursorAwareWriteTransaction
Note: It is strongly recommended to process the CheckedFuture result in an asynchronous manner rather than using the blocking get() method.
This call logically seals the transaction, which prevents the client from further changing
data tree using this transaction's cursor. Any subsequent calls to
createCursorCursor(DOMDataTreeIdentifier
or any of the cursor's methods will fail with IllegalStateException
.
The transaction is marked as submitted and enqueued into the shard back-end for processing.
