Apache Kudu is a free and open source column-oriented data store of the Apache Hadoop ecosystem. It is compatible with most of the data processing frameworks in the Hadoop environment. It provides completeness to Hadoop's storage layer to enable fast analytics on fast data.
The open source project to build Apache Kudu began as internal project at Cloudera. The first version Apache Kudu 1.0 was released 19 September 2016.
Kudu was designed and optimized for OLAP workloads. Like HBase, it is a real-time store that supports key-indexed record lookup and mutation. Kudu differs from HBase since Kudu's datamodel is a more traditional relational model, while HBase is schemaless. Kudu's "on-disk representation is truly columnar and follows an entirely different storage design than HBase/Bigtable".
Kudu 1.16.0 was released on Apr 11, 2022.
Is Kudu open source? Yes, Kudu is open source and licensed under the Apache Software License, version 2.0. Apache Kudu is a top level project (TLP) under the umbrella of the Apache Software Foundation.
Kudu 1.0.0 was released on September 19, 2016. It is the first release not considered "beta". [...] Kudu 0.5.0 (beta) was released on Sep 28, 2015. It was the first public version of Kudu.
