Walkthrough

The pull request modifies the BigQueryFormat.scala file, specifically simplifying the configuration management for BigQuery views and materialization datasets. The changes remove the previous approach of storing and restoring original configuration values, instead directly setting the viewsEnabled and materializationDataset configurations within the partitions method without subsequent restoration.

Poem

🌐 BigQuery's dance of config and view,
Simplified code, a refactoring true
No more storing, just set and go
Configurations flow, smooth and low
A cloud-born melody of Scala's might! ☁️

39-41: Good documentation links!

The references to BigQuery limitations and known issues are helpful.

41-42: Consider local configuration scope.

Setting global SparkSession configurations without restoration could affect other operations.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
