Title: Deepgreen DB: Greenplum At Speed

Greenplum is an open source Postgres-based MPP solution that can scale to hundreds of nodes and petabytes of data. Deepgreen DB is an optimized version of Greenplum. On top of a mature, market-tested data warehouse, Deepgreen DB adds data-centric code generation for speed, columnar external data engine, new interconnect and SQL-level integration with Go/Python. This talk will mainly recount the challenges of LLVM codegen on PG/GP while maintaining 100% compatibility, a necessity for market acceptance.
