描述
Difficulty: ⭐⭐⭐ (Medium)
Dependencies: Issue #9
Component: Storage
Description: Implement a sophisticated query interface that supports complex filtering, sorting, and pagination for efficient data retrieval. Create a query builder API that allows constructing complex queries programmatically with type safety, implement filtering by multiple criteria including service name patterns, version constraints, cluster names, namespaces, and labels, and add flexible sorting options by any field with ascending/descending order. Implement efficient pagination with cursor-based and offset-based approaches to handle large result sets, add comprehensive query performance optimization with proper indexing and query plan analysis, and implement query result caching with intelligent cache invalidation. Include query execution metrics that track query time and resource usage, add query validation to prevent inefficient or dangerous queries, and support query composition for reusable filter combinations.
Acceptance Criteria:
- Add complex query builder
- Implement filtering by multiple criteria
- Support sorting and pagination
- Add query performance optimization
- Implement query result caching
- Add query execution metrics
Why Now: Builds on the migration system to provide flexible data access.
