Pinterest’s journey to a Bazel monorepo
summary
Pinterest reports migrating Go and C++ monorepos to Bazel, with Java ~90% migrated and Python planned; totals include 1,365 active repos, Java seeing ~80 daily commits from 250 monthly contributors and Python 250 daily commits from 500 monthly. They build a phased coexistence with Maven, a generator called Bazelize, custom release rules that publish Docker to ECR, Debian to Artifactory and jars to S3, and a shaded jar workaround; remaining work focuses on dependency exceptions, automated upgrades and a multi-workspace strategy.
