Yingyi Bu updated SPARK-35042:
------------------------------
Description: Transform/resolve functions are called ~280k times per query
on average for a TPC-DS query, which are way more than necessary. We can reduce
those calls with early exit information and conditions. Here are some
evaluation numbers with a prototype
[doc|https://docs.google.com/document/d/1SEUhkbo8X-0cYAJFYFDQhxUnKJBz4lLn3u4xR2qfWqk/edit].
(was: It's an umbrella JIRA issue for migrating eligible transform/resolve
call sites to the version of transform/resolve functions with tree traversal
pruning support)
Summary: Support traversal pruning in transform/resolve functions and
their call sites (was: Migrate eligible transform/resolve call sites to the
