[jira] [Updated] (SPARK-35042) Support traversal pruning in
transform/resolve functions and their call sites
[ https://issues.apache.org/jira/browse/SPARK-35042?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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 version with traversal pruning)
