MuIR

Mu Intermediate Representation

Keywords: Optimizing compiler - Querying

Functional Description: This is a prototype of an intermediate language representation, i.e. an implementation of algebraic terms, rewrite rules, query plans, cost model, query optimizer, and query evaluators (including a distributed evaluator of algebraic terms using Apache Spark).
