Introduction to Apache Kudu

To deal with these previously identified trends, there are two different ways: continuously update existing Hadoop tools or redesign and develop a new component. Its objectives are:

Hybrid architecture for data scanning (scan) and random access (random access) with high performance and simplification of user complexity

High CPU efficiency, * improve the performance of advanced processors

High IO performance, making full use of advanced storage media

Support in-situ updating of data to avoid additional data processing and data movement

In order to achieve these goals, we first implemented prototypes on existing open source projects, but in the end we came to the conclusion that major changes needed to be made at the architectural level. These changes are enough to allow us to redevelop a completely new data storage system. So we started development three years ago, and now we can finally share the fruits of years of effort: Kudu, a new data storage system.
