Hello Stamatis, As Vladimir previously mentioned, we would like to present our experience working on join planning in Apache Calcite. Title: What we've learned about join order planning with Apache Calcite Abstract: Apache Calcite provides an extensive set of rules for query optimization, but how well do existing rules work for planning a large number of joins? In this talk, we will share our experience trying to push Apache Calcite to plan tens of joins using some known techniques, discuss technical challenges we faced while implementing them for Apache Calcite and potential changes to the project that may improve the issues we encountered. Planned duration: 40 min (I believe we can make it 30 if needed)
