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 a completes Hadoop's storage layer to enable fast analytics on fast data.[3]

The open source project to build Apache Kudu began as internal project at Cloudera.[4] The first version Apache Kudu 1.0 was released 19 September 2016.[5]

Comparison with other storage engines

According to the project Kudu shares some characteristics with HBase. Kudu supports "real-time store that supports key-indexed record lookup and mutation." as HBase.[6] Kudu differ from HBase since Kudu's datamodel is more traditional relational, while HBase is schemaless. Kudu's "on-disk representation is truly columnar and follows an entirely different storage design than HBase/Bigtable".[6]
