During a [recent analysis](https://gitlab.com/gitlab-com/gl-infra/scalability/-/issues/2538#note_1593195770) we forked and extended a Redis RDB dump analysis tool and published it under [cupcake-rdb](https://gitlab.com/gitlab-com/gl-infra/cupcake-rdb). The extensions enable two new types of analysis: - https://gitlab.com/gitlab-com/gl-infra/scalability/-/issues/2538#note_1593195770 - Space distribution flamegraph - https://gitlab.com/gitlab-com/gl-infra/scalability/-/issues/2538#note_1593756454 - Differential flamegraph We should document these new tools. A few places that could use with improved docs: - [cupcake-rdb README](https://gitlab.com/gitlab-com/gl-infra/cupcake-rdb/-/blob/master/README.md?ref_type=heads) - [redis runbook](https://gitlab.com/gitlab-com/runbooks/-/blob/master/docs/redis/redis.md) (could also be its own document in [the redis directory](https://gitlab.com/gitlab-com/runbooks/-/tree/master/docs/redis))
