alamb opened a new pull request, #16661:
URL: https://github.com/apache/datafusion/pull/16661

   ## Which issue does this PR close?
   
   - This is a possible alternative to 
https://github.com/apache/datafusion/pull/16573 from @findepi 
   
   I think @Omega359  had other PRs as well
   
   Relates to
   - https://github.com/apache/datafusion/issues/12892
   - https://github.com/apache/datafusion/issues/13519
   - https://github.com/apache/datafusion/issues/13212
   - https://github.com/apache/datafusion/issues/10368
   
   ## Rationale for this change
   
   The need is to access configuration settings (such as the configured 
timezone) to scalar functions during planning
   
   - https://github.com/apache/datafusion/pull/16573 proposes copying just the 
timezone. This PR proposes copying a reference to the entire config
   
   
   
   
   
   ## What changes are included in this PR?
   Add an `Arc<ConfigOptions>` to ExecutionProps when the execution is started
   
   
   
   Things I am still not happy about:
   1. This isn't with parity with UDFs yet as the entire SessionContext is 
saved there (not just config options)
   2. It isn't passed all the way to ScalarUDFs
   
   
   
   ## Are these changes tested?
   
   <!--
   We typically require tests for all PRs in order to:
   1. Prevent the code from being accidentally broken by subsequent changes
   3. Serve as another way to document the expected behavior of the code
   
   If tests are not included in your PR, please explain why (for example, are 
they covered by existing tests)?
   -->
   
   ## Are there any user-facing changes?
   
   <!--
   If there are user-facing changes then we may require documentation to be 
updated before approving the PR.
   -->
   
   <!--
   If there are any breaking changes to public APIs, please add the `api 
change` label.
   -->
