      Bug report

      For bug reports, provide this information, please:

      What Debezium connector do you use and what version?

      Oracle 2.5.0.Beta1

      What is the connector configuration?

      affects both memory and ISPN based event processors

      What is the captured database version and mode of depoyment?

      (E.g. on-premises, with a specific cloud provider, etc.)

      affects all deployments

      What behaviour do you expect?

      When transaction is abandoned due to one of the configurations, it is stored in transient memory cache so no further event of that transaction is processed. It is then removed from the cache on transaction commit

      What behaviour do you see?

      the logic was swapped when implementing this in more generic way for ISPN connector. So now EVERY transaction is added to the transient cache and never removed.

      Do you see the same behaviour using the latest relesead Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      bug introduced in 2.5.0.Beta1
