-------------------------------------
Summary: AST Node Children can be quite expensive to build due to
List resizing
Key: HIVE-22629
URL: https://issues.apache.org/jira/browse/HIVE-22629
Project: Hive
Issue Type: Improvement
Reporter: Slim Bouguerra
Assignee: Slim Bouguerra
As per the attached profile, The AST Node can be a major source of CPU and
memory churn, due to the ArrayList resizing and copy.
In my Opinion this can be amortized by providing the actual size.
