2090191 - How to Quantify an Input Transaction for Zero Data Loss in ESP 5.1 SP08 - ESP


  • An implementation of Zero Data Loss.

  • In the ESP Programmers Guide on the concept of Auto Checkpoint for Zero Data Loss, we say that
    "At the maximum checkpoint frequency of every input transaction (value of 1), all input data
    is protected except the data from the last transaction, which might not be checkpointed before a crash."

  • However, this documentation does not specify if one "input transaction" referes to a single record, a
    single transaction or a single envelope.

  • Therefore, users are unable to test and confirm the implementation of Auto Checkpoint for Zero Data Loss.



  • SAP Event Stream Processor 5.1 SP08 (and above, until the issue is fixed).

  • Implementation of the Auto Checkpoint for Zero Data Loss feature in an ESP project.
