   Thanks @holdenk for your interest and comments. 
   
   > Personally, I have some questions about how the filters are working for 
the delete use case, and I think it might be good to have some tests for the 
filter pushdown on deletes since (from my first pass reading of the code) it 
might throw an exception.
   
   I mentioned a little in the descriptions.
   ```
   This is the first part code. It changes filters to V2 filters and adds 
support to convert system functions wrapped in Spark UserDefinedScalarFunc to 
Iceberg expressions. In the following PR will add a rule to convert the system 
function call to
   ApplyFunctionExpression which could be pushed down to the data source.
   ```
   Actually, I have submitted some of the code for the rule and SQL UTs. 
However, they are split out to keep the PR small for review. I have a follow-up 
#8088 here and will be moved forward when this PR is merged.
