Summary of Changes
Hello @wu-hui, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces a foundational new data processing and query framework, known as 'Pipelines', to Firestore. This feature significantly expands the capabilities for server-side data manipulation, allowing users to perform complex transformations, aggregations, and advanced filtering operations that go beyond traditional query limitations. The implementation includes a new expression evaluation engine and ensures compatibility with existing query patterns, providing a flexible and powerful tool for data management.
Highlights
- New Pipelines API: Introduced a powerful new 'Pipelines' API for advanced query and data transformation capabilities within Firestore. This API allows for complex data manipulation and aggregation directly on the server.
- Expanded Query Operations: The new Pipelines API supports a wide array of operations including aggregation (count, sum, average), advanced filtering (logical, comparison, array, string, regex), data transformation (add/remove fields, select, replace), and structural operations (unnest, union).
- Integration with Existing Queries: Existing Firestore Query objects can now be converted into the new Pipeline format, ensuring compatibility and providing a migration path for enhanced functionality.
- Kotlin-based Expression Engine: A new Kotlin-based expression evaluation engine has been implemented to power the Pipelines API, enabling robust and extensible data processing logic.
- Internal Refinements: Significant internal refactoring was performed across various modules, including number comparison helpers, document/field path handling, and value serialization, to support the new pipeline architecture.

Code Review
This pull request introduces a significant new feature: a Pipeline API for Firestore queries. This provides a more expressive and flexible way to query data, similar to aggregation pipelines in other databases. The changes are extensive, including the new fluent API, the underlying execution logic, a compatibility layer to convert existing Query objects, and a comprehensive suite of tests. Overall, this is a well-implemented feature. I've identified one critical compatibility issue and a few minor issues in the test files.
