> Eliminate unnecessary collect operation
> ---------------------------------------
>
> Key: SPARK-51704
> URL: https://issues.apache.org/jira/browse/SPARK-51704
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.0.0, 3.5.5, 4.1.0
> Reporter: zhoubin
> Priority: Minor
> Labels: pull-request-available
>
> Change the `TreeNode` operation from `{{{}collect`{}}} to
> `{{{}collectFirst`,{}}} when it is supposed to find the first qualified node
> rather than apply function through out all the node and it's child, this
> function should not take any effect or make any change to the node which
> applied for.
> Any scenarios satisfy below factors:
> # Apply certain operation recursively on the `TreeNode` including itself
> # The final purpose is to find the first qualified node in a pre order way
> # The final purpose is to verify that there is at least one node which
> satisfy the requirement
> # Partial function applied should not effect the node or other related
> Especially, the last factor should be reviewed carefully.
