### [Taming the monorepo beast: Our journey to a leaner, faster GitLab repo](https://yomu.fyi/post/taming-the-monorepo-beast-our-journey-to-a-leaner-faster-gitlab-repo.md)

Grab’s decade-old Go monorepo grew to 12.7 million commits, 73GB of Git-tree metadata, 176GB of blobs, 12 million references, and 444,000 files, causing replication lag, slow developer workflows, and GitLab operational bottlenecks. A staging proof of concept compared full and single-commit histories under production-like load: replication delay fell from 160–240 seconds to 1–2.5 seconds, nearly a 100x improvement. Because custom migration tooling processed about 100 commits per hour, the team retained commits reachable from more than 2,000 critical tags, one month of recent history, and simplified merge commits, while archiving older history. The resulting prune reduced commits by 99.9%, improved replication performance by 99%, preserved code and tags without data loss, and left teams with minor migration adjustments.

Grab introduced a rich-text, WYSIWYG editor in its TechDocs portal to help non-engineering contributors work within a Docs-as-Code process despite limited familiarity with Markdown and GitLab. The editor keeps GitLab as the central storage system, uses Lexical to import and export Markdown, and supports page reordering, renaming, deletion, formatting, diagrams, and switching between normal and Markdown views. Three user journeys cover editing existing TechDocs and creating stand-alone or entity-linked documentation, with GitLab OAuth2, merge-request creation, repository access checks, and scheduler-based entity-catalog registration after merges. A phased rollout added drafts, image uploads, diagram integrations, concurrent-session visibility, and live preview, while pending-MR displays and conflict-resolution tools address collaboration risks.


### [Continuous Deployment with GitLab](https://yomu.fyi/post/continuous-deployment-with-gitlab.md)
- Company: [Fly.io](https://yomu.fyi/company/fly-io.md)
- Published: Mar 23, 2020

The guide shows how to set up continuous deployment from GitLab CI/CD to a Fly application, using the small Go hellofly example. GitLab supplies the repository contents to a Runner defined by the golang:1.13 image, while a before\_script installs curl and downloads flyctl through Fly’s installation script. A deploy job then runs flyctl deploy, which builds and deploys the application from a committed fly.toml file. Authentication is configured by obtaining a token with flyctl auth token and storing it as a protected, masked FLY\_API\_TOKEN CI/CD variable in the repository settings. After .gitlab-ci.yml is committed and pushed, GitLab starts the deployment job, while the guide notes that more advanced pipeline structures and triggers remain available.
