Confluent has introduced a preview release of its platform, which includes powerful new capabilities for KSQL and Confluent Control Center, including a brand new KSQL UI that provides a graphical interface to view and edit queries, stream data, and tables. The control center also offers improved features such as viewing broker configurations, inspecting Kafka topics, monitoring consumer lag, and enabling non-windowed usage of aggregation functions on tables. Additionally, the preview release includes improvements to the KSQL REST API, including support for specifying timestamp formats when creating streams or tables, and preventing dropping of active streams or tables without terminating dependent queries. Users can share their feedback through the Confluent Community Slack channel or by contributing to the KSQL project on GitHub.
