- Integrated Redis caching in BusinessActivityComplexesService for findAll and findOne methods.
- Enhanced ConsumersService with Redis caching for findAll and findOne methods.
- Introduced cache invalidation for partner consumers and business activities.
- Created RedisKeyMaker utility for generating cache keys for consumers, partners, and POS.
- Implemented cache invalidation services for partners and POS.
- Added Redis service methods for JSON handling and key deletion by patterns.
- Updated goods service to include caching and invalidation for goods list.
- Introduced DTO for updating goods.
