Summary of Changes

Hello @jaredwray, 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 Keyv MySQL storage adapter by introducing batch operations for setting and checking key existence. The new setMany and hasMany methods allow applications to perform these common tasks more efficiently, reducing the number of database queries and improving overall performance when dealing with multiple key-value pairs.

Highlights

  • New setMany method: Introduced a setMany method to efficiently set multiple key-value pairs in a single operation, utilizing MySQL's INSERT ... ON DUPLICATE KEY UPDATE.
  • New hasMany method: Added a hasMany method to check the existence of multiple keys simultaneously, returning an array of booleans corresponding to the input keys.
  • Documentation Updates: Updated the README.md file to include documentation and usage examples for the newly added setMany and hasMany methods.
Changelog
  • storage/mysql/README.md
    • Added documentation for the new .setMany(entries) method.
    • Added documentation for the new .hasMany(keys) method.
  • storage/mysql/src/index.ts
    • Imported the KeyvEntry type for type safety.
    • Implemented the setMany method to handle batch insertion and updating of key-value pairs.
    • Implemented the hasMany method to efficiently check for the existence of multiple keys.
Activity
  • The author, jaredwray, initiated this pull request to add setMany and hasMany features to the MySQL adapter.
  • The author indicated that tests for these new features have been added, achieving 100% code coverage.
  • The changes are categorized as a new feature for the MySQL storage adapter.

Code Review

This pull request introduces setMany and hasMany methods to the MySQL storage adapter, along with corresponding documentation updates. The implementation is generally good, but I've identified a bug in setMany that occurs when an empty array is provided, which could lead to an SQL error. I've also suggested an optimization for hasMany to prevent an unnecessary database call with an empty key list. My review includes code suggestions to address these points.
