This meeting will start with a 20-minute technology discussion topic, followed by a contributor discussion and open Q&A. 20-minute User Tech Talk - GPORCA: The Next Generation Query Optimizer is Now Open Source GPORCA is newly open source advanced query optimizer that is a subproject of Greenplum Database open source project. GPORCA is the query optimizer used in commercial distributions of both Greenplum and HAWQ. In these distributions GPORCA has achieved 1000x performance improvement across TPC-DS queries by focusing on three distinct areas: Dynamic Partition Elimination, SubQuery Unnesting, and Common Table Expression. Now that GPORCA is open source, we are looking for collaborators to help us realize the ultimate dream for GPORCA - to work with any database. The new breed of data management systems in Big Data have to process so much data that optimization mistakes are magnified in traditional optimizers. Furthermore, coding and manual optimization of complex queries has proven to be hard. In this session, Venkatesh will discuss: - Overview of GPORCA - How to add GPORCA to HAWQ with a build option - How GPORCA could be made to work with any database - Future vision for GPORCA and more immediate plans - How to work with GPORCA, and how to contribute to GPORCA Speaker: Venkatesh Raghavan - Staff 1, Query Processing Team Venky is a core member of Pivotal’s Query Processing team. He holds multiple patents focusing on Big Data processing and database design. He joined Pivotal, then Greenplum, after received his Ph.D. from the Worcester Polytechnic Institute in Massachusetts, where he focused on database technologies. Standing agenda: -Open Jiras, and ways to contribute -Next release coordination -Open Q&A Please join us on February 23, 2016 at: https://pivotalcommunity.adobeconnect.com/hawqnest/ 2/23 San Francisco, CA 9:00 AM PST UTC-8 hours 2/23 New York, NY 12:00 PM EST UTC-5 hours ---------------- If you have never attended an Adobe Connect meeting before: Test your connection: https://pivotalcommunity.adobeconnect.com/common/help/en/support/meeting_test.htm Get a quick overview: http://www.adobe.com/products/adobeconnect.html Thanks, Karen
