 ============================
 
 Apache MRQL (pronounced miracle) is a query processing and optimization
 system for large-scale, distributed data analysis. MRQL (the MapReduce
 Query Language) is an SQL-like query language for large-scale data
 analysis on a cluster of computers. The MRQL query processing system
