  • Fast and Flexible Query Analysis at MapD with Apache Calcite

    Where direct reuse failed, we were able to extract common abstractions idiomatic to both the legacy and the new Calcite frontend. Our in-house frontend didn''t use canonical relational algebra nodes, but the building blocks were similar enough to make migration possible. Calcite is a Java project, so integration with C++ isn''t entirely trivial.
