What is "sawzall"

Sawzall may refer to:

• Sawzall (programming language), a domain-specific programming language
• A brand of reciprocating saw manufactured by the Milwaukee Electric Tool Company

Sawzall is a procedural domain-specific programming language, used by Google to process large numbers of individual log records. Sawzall was first described in 2003, and the szl runtime was open-sourced in August 2010. However, since the MapReduce table aggregators have not been released, the open-sourced runtime is not useful for large-scale data analysis of multiple log files off the shelf.
