Class OffsetRecord

  • public class OffsetRecord
extends java.lang.Object
    If OffsetRecord is initialized with a serializer that contains SchemaReader, old version of server codes will be able to deserialize OffsetRecord that is serialized with a newer protocol version, which can happen after rolling back a server release with new protocol version to an old server release with old protocol version.

      • getUpstreamOffset

        public long getUpstreamOffset​(java.lang.String kafkaURL)
        The caller of this API should be interested in the largest known upstream offset. For example, during re-balance, a new leader is elected to consume a partition from scratch; the partition in VT looks like this: SOP, data messages from batch..., EOP, TS, some data messages from RT... Leader shouldn't act on the TS message the moment it consumes TS, but instead, it should consume all the messages in the VT including all the existing real-time messages in VT, in order to resume consumption from RT at the largest known upstream offset to avoid duplicate work. In this case, leader is still consuming VT, so it would return VT offset; users should call this API to get the latest upstream offset.
