Walkthrough

The changes introduce a new optional field, default_dialect, to the SqlQueriesSourceConfig class in the sql_queries.py file. This field allows users to specify the SQL dialect for parsing queries, overriding the automatic detection feature. The default_dialect is integrated into the _process_query method of the SqlQueriesSource class and is documented within the class definition. The overall structure of the class remains unchanged, with the new field enhancing the query processing capabilities.

Changes

File Path	Change Summary
metadata-ingestion/src/datahub/ingestion/source/sql_queries.py	Added default_dialect: Optional[str] field to SqlQueriesSourceConfig and integrated it into _process_query method. Documented the new field in the class definition.

Poem

🐰 In the land of SQL, where queries play,
A new dialect joins the fray today!
With default_dialect, oh what a delight,
Parsing made easy, everything feels right!
So hop along, let the queries flow,
In the world of data, we’re ready to grow! 🌼

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.
