[GitHub] [arrow-datafusion] avantgardnerio commented on issue #5357: `supports_filter_pushdown()` receives broken-up `filter`s

   replace "database" with TableProvider and I agree with you there
   
   > What would be the reason to push down certain parts?
   Only that this is how it happens now. I assume others are attached to the present behavior? It seems way more simple to have the TableProvider split the conjunction (if it wants) than have it re-assemble the original filter from a bunch of separate calls.
