------------------------------------------
Summary: AST tree processing is suboptimal for tree with large
number of nodes
Key: HIVE-24362
URL: https://issues.apache.org/jira/browse/HIVE-24362
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
In hive the children information is stored as list of objects. During
processing of the children of a node, the list of object is converted to list
of Nodes. This can cause large compilation time if the number of children is
large. The list of children can be cached in the AST node to avoid this
re-computation.
