  • Method Details

    • 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
