Summary of Changes

Hello, 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 primarily updates the librarian tool's image, which subsequently led to the removal of numerous files associated with the google-cloud-bigtable client library. This suggests a cleanup or re-generation process where the Bigtable client library components were either deprecated, moved, or failed to generate correctly, necessitating their removal from the repository.

Highlights

• Librarian Image Update: The librarian tool's image reference in .librarian/state.yaml was updated to a new SHA256 hash, indicating a new version of the Python Librarian Generator.
• Removal of google-cloud-bigtable Client Library Files: A substantial number of files related to the google-cloud-bigtable client library, specifically for bigtable_admin and bigtable_admin_v2 services, were removed. This includes core Python files, GAPIC metadata, versioning, and documentation.
• Documentation Cleanup: Several documentation files under docs/admin_client/ and docs/summary_overview.md were removed, likely corresponding to the removal of the google-cloud-bigtable client library components.

Code Review

This pull request appears to be the result of a failed automated generation process. The pull request description explicitly states that generation failed for google-cloud-bigtable, and the diff shows the deletion of a large number of critical source files from the google/cloud/bigtable_admin_v2 and google/cloud/bigtable_admin packages. This is likely unintentional and would break the library. This pull request should not be merged in its current state. The underlying generation issue needs to be fixed and a new pull request should be created.

google/cloud/bigtable_admin_v2/init.py (1-382)

This file, along with most of the google.cloud.bigtable_admin_v2 package, is being deleted. This appears to be due to a failed generation process as noted in the pull request description. Deleting these core files will break the library. This change should be reverted and the generation issue should be investigated.
