Episode notes
Resque's Complexity Triggered SolidQ
- Rescue became overly complex with many custom patches and forks over time at 37signals.
- Rosa and her team decided it "cannot be so complicated" and thus started building Solid Queue.
Build With Clear Requirements
- Build new systems with precise requirements in mind, learned from past patching struggles.
- Try to avoid replicating quirks and edge cases from legacy systems when possible.
Migrated Hay Before Basecamp
- The team chose to migrate the existing app Hay to SolidQ for realistic testing.
- Hay was less critical than Basecamp but had similar quirks and setup requiring the new job queue.
