You've made several commits to your feature branch. Before merging into the main branch, you want to consolidate the changes into a single, clear commit. What Git technique would help achieve this?

• A.git cherry-pick specific commits from your branch and reapply them.
• B.Run git rebase main followed by git commit -amend.
• C.Use git rebase -i (interactive rebase) to squash commits together.
• D.Manually copy your files into a new branch, commit, and issue a pull request.

Performance Bottleneck

• A.Implement database-level indexes on columns involved in the joins, if appropriate.
• B.Introduce CTEs to pre-calculate aggregated data or common subexpressions, especially if reused repeatedly.
• C.Add -full-refresh to dbt run on the model to ensure downstream models don't cause errors.
• D.Run EXPLAIN or equivalent on the compiled query to pinpoint the most expensive operations.

Which of the following are essential elements of a well-structured pull request description?

• A.References to related issues in the project tracker, if applicable.
• B.Detailed logs of each Git command used during development.
• C.A concise title summarizing the overall changes.
• D.Explanations of the reasoning behind major changes and implementation choices.

You've implemented a macro to standardize descriptions across a set of models. After updating the macro and regenerating docs, the changes don't seem to be reflected. What could be the cause?

• A.The documentation generator is caching the old version of the macro.
• B.The macro might only be applied to specific model types.
• C.Your macro implementation has a subtle logic error.
• D.Changes to macros sometimes require a full re-compilation of all models for the updates to take effect in the documentation.
