Committer (Flink : 2.0-SNAPSHOT API)

Type Parameters:

CommT - The type of information needed to commit the staged data

All Superinterfaces:

AutoCloseable

All Known Implementing Classes:

FileCommitter
```
@Public
public interface Committer<CommT>
extends AutoCloseable
```
The Committer is responsible for committing the data staged by the CommittingSinkWriter in the second step of a two-phase commit protocol.
A commit must be idempotent: If some failure occurs in Flink during commit phase, Flink will restart from previous checkpoint and re-attempt to commit all committables. Thus, some or all committables may have already been committed. These Committer.CommitRequests must not change the external system and implementers are asked to signal Committer.CommitRequest.signalAlreadyCommitted().
