Replacing Sawzall — a case study in domain-specific language migration
Since the logs proxy decouples our data access policy from the programming language used for analysis, individual teams now have more freedom to choose the language that best fits their needs. However, since analysis libraries can often get very complicated, and multiple teams often share common data sources, there is an economy of scale in choosing a common language for most analysis.

At Google, most Sawzall analysis has been replaced by Go. Go has the advantage of being a relatively small language which is easy to learn and integrates well with Google’s production infrastructure. Fast compile times and garbage collection make Go a natural fit for iterative development. To ease the process of migrating from Sawzall, we’ve developed a set of Go libraries that we call Lingo (for Logs in Go). Lingo includes a table aggregation library that brings the powerful features of Sawzall aggregation tables to Go, using reflection to support user-defined types for table keys and values. It also provides default behavior for setting up and running a MapReduce that reads data from the logs proxy. The result is that Lingo analysis code is often as concise and simple as (and sometimes simpler than) the Sawzall equivalent.
