Summary of Changes

Hello @mutianf, 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 enhances the Bigtable I/O connector by adding support for specifying row filters as a text proto string. This feature allows users to define complex row filters dynamically, particularly useful in templated pipelines where filter configurations might be provided as strings. The change introduces a new method withRowFilterTextProto in BigtableIO.Read and updates the underlying read options and parsing logic to handle this new filter type, ensuring compatibility and proper precedence with existing RowFilter options.

Highlights

  • New Row Filter Option: Introduced withRowFilterTextProto to BigtableIO.Read, allowing users to specify Bigtable row filters as a TextFormat string via a ValueProvider<String>. This enables dynamic filter configuration, especially useful for templated pipelines.
  • Filter Precedence: If both withRowFilter (using a RowFilter object) and withRowFilterTextProto (using a text proto string) are provided, the existing withRowFilter takes precedence.
  • Internal Handling: The BigtableReadOptions now stores the ValueProvider<String> for the text proto filter, and the BigtableIO.Read.Reader class includes logic to parse this string into a RowFilter object when needed.
  • Test Coverage: A new test case, testReadingWithRowFilterTextProto, was added to BigtableIOTest to validate the functionality of reading rows using the new text proto filter option.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.
