Join us for an insightful discussion on 1 October, 2024 at 11:00 AM ET to get an overview of the hash join algorithm which is a fundamental technique in database systems, widely used for executing join operations efficiently, especially when dealing with large datasets. The existing hash join implementation of CDE has some drawbacks while processing queries involving large number of payload columns and wide payload columns (fixed-length, variable-length or mixed). The session delves into the improvements implemented in the db2 columnar engine's hash join execution, with the primary objectives of reducing memory usage and improving overall performance. Ajith Krishnan R and Ian Finlay will also cover an overview of Hash Join, drawbacks of existing implementation, the proposed solution, and performance metrics comparing the feature-enabled and disabled scenarios.
