Source topics

Select the source cluster topic to replicate

K2K supports the replication of multiple topics, which can be specified by name or with a regular expression.

By Name

This configuration block demonstrates how to replicate a specific list of topics. The topic key is an array that contains the exact names of the topics you want to replicate, in this case "prod-topic-1" and "prod-topic-2".

replication:
  - source:
      topic:
        - "prod-topic-1"
        - "prod-topic-2"

By Pattern

This configuration block demonstrates how to replicate topics that match a specific naming pattern. The topic key is a string containing a regular expression. In this example, "prod.*" will select and replicate all topics whose names begin with "prod".

replication:
  - source:
      topic: "prod.*"
