Golden Gate with Kafka Connect Adapter Checkpoint Files

in GoldenGate, Streams and Distributed Database (MOSC) 1 commentAnswered

Hello World,


I'm running a Golden Gate installation with:

  • OGG for Oracle 19.1.0.0.4
  • OGG for Big Data 19.1.0.0.5
  • Confluent Kafka 6.0

Golden Gate extracts transactions from the Oracle Database with an Integrated Extract.

The transactions are loaded into Kafka Topics by a Replicat with Kafka Connect Handler.

In this configuration I cannot have a Checkpoint table and all checkpoints are written to the .cpr and .cpj files.

So the Checkpoint files become a de facto single point of failure. If the files become corrupted due to a very unlucky process crash, bug or infrastructure failure, it will be very hard to recover from the incident without at least a couple of records missing or duplicated.
