Usage

Although tMapRStreamsCommit can be used as an end component in a Subjob flow or can be called independently as its own Subjob, it is typically used standalone to commit a batch of offsets in one go. If you need to commit offsets regularly, it is recommended to use the Auto-commit feature in tMapRStreamsInput.
