Topics included in a replication flow

When defining a replication flow you need to define which topics in the source Apache Kafka® cluster to include or exclude from the cross-cluster replica.

The topics parameter dictates which topics to include in the replica and can be provided as list of regular expressions in Java format. The same is also valid for the topics blacklist parameter defining which topics to exclude.

Example: topic inclusion and exclusion regular expressions

If you need to define a replication flow including the topic warehouse.operations and any topic starting with customer., but excluding the topic customer.support then the following regular expression can be used:

  • Topics: customer\\..* and warehouse\\.operations

  • Topics Blacklist: customer\\.support
