We installed ORACLE GOLDEN GATE STREAM ANALYTICS from marketplace on an OCI instance.
We built pipelines that read a data stream from an external Kafka cluster. The configuration obviously involves user-id and group-id.
The pipelines are working correctly.
However, we have a doubt about building different pipelines that read from the same Kafka topic: is it possible to build two pipelines that use the same user-id and group-id and consume data from the same topic kafka? Or are messages consumed by only one of the two pipelines?
Reading from the Kafka documentation we see that:
- within same group is not possible: two consumers (Consumer 1, 2) within the same group (Group 1) can't consume the same message from partition (Partition 0).
- between different groups is possible: two consumers in two groups (Consumer 1 from Group 1, Consumer 1 from Group 2) can consume the same message from partition (Partition 0).
Is this also true for data consumption from topics via OSA pipelines?
