-----------------------------------
Labels: pull-request-available (was: )
> Collapse inner Cast from DecimalType to DecimalType
> ---------------------------------------------------
>
> Key: SPARK-52461
> URL: https://issues.apache.org/jira/browse/SPARK-52461
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Mihailo Aleksic
> Priority: Major
> Labels: pull-request-available
>
> When coercing an expression from DecimalType to DecimalType, remove the inner
> Cast if it is not user-specified one and if the outer DecimalType is wider
> than inner (precision and scale are greater) - or in other words, if it is
> redundant. Do that only in case SQLConf.COLLAPSE_INNER_CAST_TO_DECIMAL value
> is true.
> This is needed to make single-pass and fixed-point implementations compatible.
