Examples of org.apache.flume.Transaction.begin()

org.apache.flume.Transaction.begin()

Starts a transaction boundary for the current channel operation. If a transaction is already in progress, this method will join that transaction using reference counting.

Note: For every invocation of this method there must be a corresponding invocation of {@linkplain #close()} method. Failureto ensure this can lead to dangling transactions and unpredictable results.
