Connect with Confluent Cloud Apache Kafka® cluster

Confluent Cloud Apache Kafka is a fully managed distributed data streaming platform, deployable in a cloud, maintained by Confluent. This section provides you with information on how to connect Confluent Cloud Apache Kafka cluster with Klaw. The following functionalities are available in Klaw for Confluent Cloud:

  • Create topics
  • Delete topics
  • Create ACLs
  • Delete ACLs
  • Sync topics
  • Sync ACLs



  • Set up the connection between the Klaw APIs (Klaw Core API and Klaw Cluster API), see klaw-core-with-clusterapi. This involves configuring the klaw.clusterapi.url setting in the Klaw UI and testing the connectivity to ensure the two APIs can communicate.
  • Both the Klaw APIs are running on SSL/HTTPS.

  10. Configure the API key, API secret, URIs to connect to Confluent Cloud Apache Kafka clusters by copying and editing the following lines:

    #Example :
    • Copy the {cluster_id} from the Confluent Cloud portal (Cluster Settings > General > Identification > Cluster ID) and insert into the API URI.
    • Copy the API key/secrets from Confluent Cloud > API Keys.
    • For the lines starting with clusterid, replace clusterid with the Klaw Cluster ID. Save the file.
