Description

This PR adds time-related data type support in the generic function of object authenticity management. Similar to the ScalarDL SQL grammar, you can specify it with text literals that follow a specific format to put DATE, TIME, TIMESTAMP, and TIMESTAMPTZ values.

Summary of Changes

Hello @jnmt, 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 significantly enhances the PutToMutableDatabase generic function by introducing support for various time-related data types. This enables users to store and manage DATE, TIME, TIMESTAMP, and TIMESTAMPTZ values directly within the mutable database, improving data fidelity and consistency. The changes include schema updates, new formatting utilities, and robust input validation to ensure data integrity.

Highlights

  • New Data Type Support: The generic function PutToMutableDatabase now supports DATE, TIME, TIMESTAMP, and TIMESTAMPTZ data types, allowing for more precise time-related data storage.
  • Schema and Formatting: Introduced new DateTimeFormatter constants for standard date and time literal formats, and updated the objects-table-schema.json to reflect the use of TIMESTAMP for the registered_at column.
  • Robust Input Validation: Implemented parsing logic for the new time-related data types, including strict validation to ensure that input strings conform to the expected formats, throwing ContractContextException for invalid inputs.
  • Expanded Test Coverage: Added comprehensive unit and integration tests to verify the correct handling of the new time-related data types, including successful data insertion and error handling for malformed inputs.

Pull Request Overview

This PR adds support for time-related data types (DATE, TIME, TIMESTAMP, and TIMESTAMPTZ) to the generic function for putting data to mutable databases. The implementation enables proper parsing, validation, and storage of these temporal data types with standardized formatters.

  • Adds support for DATE, TIME, TIMESTAMP, and TIMESTAMPTZ data types in the PutToMutableDatabase function
  • Implements proper parsing and validation logic for time-related data with standardized formatters
  • Updates the database schema to use TIMESTAMP instead of BIGINT for the registered_at column

Code Review

This pull request adds support for time-related data types (DATE, TIME, TIMESTAMP, TIMESTAMPTZ) in the generic PutToMutableDatabase function. The changes include new DateTimeFormatter constants, updates to the function logic to handle these new types, and corresponding additions to integration and unit tests. The implementation is solid, but I've found a few areas for improvement: in Constants.java, one of the new formatters is missing strict parsing settings; in PutToMutableDatabase.java, there's a piece of unreachable code that should be removed; and in PutToMutableDatabaseTest.java, a duplicated helper method was added which can be removed to reduce code duplication. These are minor issues, and addressing them will improve the code's consistency and maintainability. Overall, great work on adding this new functionality.
