Confluent Clusters (ksqldbcm/v2) API
[](#section/Versioning/API-Lifecycle-Policy) `Cluster` represents a ksqlDB runtime that you can issue queries to using its API endpoint. It executes SQL statements and queries which under the hood get built into corresponding Kafka Streams topologies. The API allows you to list, create, read, and delete your ksqlDB clusters.
