Supercharging IDE and Sync Performance
summary
Airbnb replaces inactive Gradle modules with published AARs versioned by content hash, stores a version-map in S3 tied to main branch commits, and CI publishes changed modules so a sync only configures the focused modules. Settings.gradle is overloaded to swap project references for AARs during sync, a background job preloads AARs every four hours, and an IntelliJ plugin adds a focus sync button and a dev‑app panel for incremental module loading. Results: 75% lower sync time (avg <30s), 70% fewer IDE hangs, 50% less code analysis time.
