Data Marts on Data Lakehouse: A Major Migration from Greenplum 6

We are going to discuss the real experience of migrating data marts from a monolithic solution based on Greenplum 6 to the Data Lakehouse stack, paying attention to how to make this process the least painful for users. You will learn what non-obvious problems you will have to face and how to build processes so that the new architecture is more efficient than the legacy solution, rather than its less productive copy.
