Josh combines the advantages of monorepos with those of multirepos by leveraging a blazingly-fast, incremental, and reversible implementation of git history filtering. Traditionally, history filtering has been viewed as an expensive operation that should only be performed to fix issues with a repository, such as purging big binary files or removing accidentally-committed secrets, or as part of a migration to a different repository structure, like switching from multirepo to monorepo (or vice versa).
