A large codebase cannot be searched with naive indexing algorithms. In order to search through a codebase the size of Uber’s it is necessary to build a much more sophisticated indexing system than simple pure text search.

SourceGraph is a system for universal code search. It allows developers to more easily onboard to a new codebase, make large refactors, and perform other tasks. SourceGraph can integrate with source control systems, IDEs, and other tools to fit comfortably into an engineer’s workflow.

Beyang Liu is a co-founder of SourceGraph and he joins the show to talk about how codebases can become large and unwieldy, and the tooling that SourceGraph offers to make these codebases easier to work with.
