- Method Detail
  - firstOffset
```
long firstOffset()
```
    The first offset in the stream.
    
    Returns:
    
    first offset in the stream
    
    Throws:
    
    NoOffsetException - if there is no first offset yet
  - committedChunkId
```
long committedChunkId()
```
    The ID (offset) of the committed chunk (block of messages) in the stream.
    It is the offset of the first message in the last chunk confirmed by a quorum of the stream cluster members (leader and replicas).
    The committed chunk ID is a good indication of what the last offset of a stream can be at a given time. The value can be stale as soon as the application reads it though, as the committed chunk ID for a stream that is published to changes all the time.
    
    Returns:
    
    committed offset in this stream
    
    Throws:
    
    NoOffsetException - if there is no committed chunk yet
