> Post order walker for iterating over expression tree

> Key: HIVE-22079
> URL: https://issues.apache.org/jira/browse/HIVE-22079
> Project: Hive
> Issue Type: Improvement
> Components: Logical Optimizer, Physical Optimizer
> Affects Versions: 4.0.0
> Reporter: Vineet Garg
> Assignee: Vineet Garg
> Priority: Major
> Attachments: HIVE-22079.1.patch, HIVE-22079.2.patch,

>
> Current {{DefaultGraphWalker}} is used to iterate over an expression tree.
> This walker uses hash map to keep track of visited/processed nodes. If an
> expression tree is large this adds significant overhead due to map lookup.
> For an expression trees we can instead use post order traversal and avoid
> using map.
