Subscription Cursors

The cursors in the Subscription API have the following structure:

The fields are:

  • partition: The partition this batch belongs to. A batch can only have one partition.
  • offset: The offset of this batch. The offset is server-defined and opaque to the client - clients should not try to infer or assume a structure.
  • event_type: Specifies the event-type of the cursor (as in one stream there can be events of different event-types)
  • cursor_token: The cursor token generated by Mambu.
