# Issue #165: BullMQ Module Setup

## Objective

Create BullMQ module that shares the existing Valkey connection for job queue processing.

## Approach

1. Examine existing Valkey configuration patterns
2. Write tests for BullMQ module (TDD - RED)
3. Implement BullMQ module components
4. Integrate with app.module.ts
5. Run quality gates

## Progress

- [x] Create scratchpad
- [x] Examine existing Valkey configuration
- [x] Write unit tests (RED phase)
- [x] Create queue definitions
- [x] Implement BullMQ service
- [x] Implement BullMQ module
- [x] Add to app.module.ts
- [x] Run quality gates (typecheck, lint, build, test)
- [x] Commit changes

## Testing

- Unit tests for BullMQ service
- Queue creation verification
- Valkey connection validation

## Notes

- Prerequisites: Issue #163 completed (dependencies installed)
- Must reuse VALKEY_URL from environment
- Queue naming convention changed from `mosaic:jobs:*` to `mosaic-jobs-*` (BullMQ doesn't allow colons)
- Unit tests pass without requiring Redis connection (tests validate configuration and structure)
- All quality gates passed: typecheck, lint, build, test

## Implementation Details

- Created 4 queues: main, runner, weaver, inspector
- Follows existing Valkey module patterns
- Uses ioredis connection under the hood (BullMQ requirement)
- Includes health check methods for monitoring
- Proper cleanup in onModuleDestroy lifecycle hook
