Optimized joins & filtering with Bloom filter predicate in Kudu

Note: This is a cross-post from the Cloudera Engineering Blog Optimized joins & filtering with Bloom filter predicate in Kudu

Cloudera’s CDP Runtime version 7.1.5 maps to Apache Kudu 1.13 and upcoming Apache Impala 4.0

Introduction

In database systems one of the most effective ways to improve performance is to avoid doing unnecessary work, such as network transfers and reading data from disk. One of the ways Apache Kudu achieves this is by supporting column predicates with scanners. Pushing down column predicate filters to Kudu allows for optimized execution by skipping reading column values for filtered out rows and reducing network IO between a client, like the distributed query engine Apache Impala, and Kudu. See the documentation on runtime filtering in Impala for details.

CDP Runtime 7.1.5 and CDP Public Cloud added support for Bloom filter column predicate pushdown in Kudu and the associated integration in Impala.
