Sawzall is a procedural language developed for parallel analysis of very large data sets (such as logs). It provides protocol buffer handling, regular expression support, string and array manipulation, associative arrays (maps), structured data (tuples), data fingerprinting (64-bit hash values), time values, various utility operations and the usual library functions operating on floating-point and string values. For years Sawzall has been Google's logs processing language of choice and is used for various other data analysis tasks across the company.
