Note: This is a cross-post from the Cloudera Engineering Blog Transparent Hierarchical Storage Management with Apache Kudu and Impala

When picking a storage option for an application it is common to pick a single storage option which has the most applicable features to your use case. For mutability and real-time analytics workloads you may want to use Apache Kudu, but for massive scalability at a low cost you may want to use HDFS. For that reason, there is a need for a solution that allows you to leverage the best features of multiple storage options. This post describes the sliding window pattern using Apache Impala with data stored in Apache Kudu and Apache HDFS. With this pattern you get all of the benefits of multiple storage layers in a way that is transparent to users.

Most of the posts in the Kudu blog have been written by the project’s committers and are either technical or news-like in nature. We’d like to hear how you’re using Kudu in production, in testing, or in your hobby project and we’d like to share it with the world!

This summer I got the opportunity to intern with the Apache Kudu team at Cloudera. My project was to optimize the Kudu scan path by implementing a technique called index skip scan (a.k.a. scan-to-seek, see section 4.1 in [1]). I wanted to share my experience and the progress we’ve made so far on the approach.
