Open alamb opened this issue 1 year ago • 3 comments

Which issue does this PR close?

Part of https://github.com/apache/datafusion/issues/10855

Rationale for this change

The current rewrite_expr.rs example has three distinct examples:

  1. Using DataFusion LogicalPlanning without execution
  2. Implementing an AnalyzerRule
  3. Implementing an OptimizerRule

Each I think should be its own example to make them easier to find and more full featured

What changes are included in this PR?

  1. Add example sql_frontend.rs
  2. Improve documentation of TableSource trait

Are these changes tested?

Yes by CI

Are there any user-facing changes?

🤔 this might also make https://github.com/apache/datafusion/blob/main/datafusion/sql/examples/sql.rs redundant
