Introducing the Externalized Kudu Connector We are pleased to announce the revival of a connector that makes it possible for Flink to interact with Apache Kudu. The original connector existed as part of the Apache Bahir project, which was moved into the attic. Despite this, we saw interest to keep the Kudu connector updated, hence the community agreed to externalize it as a standalone connector in accordance with the current connector development model. For more information about the externalization process, see FLIP-439.
