Begin a transaction for this thread.
<p>
Transactions may nest. If the transaction is not in progress, then a database connection is
obtained and a new transaction is started. Otherwise, a nested transaction is started.
<p>
Each call to {@code newTransaction} must be matched exactly by a call to
{@link Transaction#end()}. To mark a transaction as successful, call
{@link Transaction#markSuccessful()} before calling {@link Transaction#end()}. If the
transaction is not successful, or if any of its nested transactions were not successful, then
the entire transaction will be rolled back when the outermost transaction is ended.
<p>
Transactions queue up all query notifications until they have been applied.
<p>
Here is the standard idiom for transactions:

<pre>{@code
try (Transaction transaction = db.newTransaction()) {
...
transaction.markSuccessful();
}
}</pre>

Manually call {@link Transaction#end()} when try-with-resources is not available:
<pre>{@code
Transaction transaction = db.newTransaction();
try {
...
transaction.markSuccessful();
} finally {
transaction.end();
}
}</pre>
