Maxim Gekk resolved SPARK-31445.
--------------------------------
Resolution: Won't Fix
> Avoid floating-point division in millisToDays
> ---------------------------------------------
>
> Key: SPARK-31445
> URL: https://issues.apache.org/jira/browse/SPARK-31445
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.5
> Reporter: Maxim Gekk
> Priority: Minor
>
> As the benchmark https://github.com/MaxGekk/spark/pull/27, and comparison to
> Spark 3.0+an optimisation of fromJavaDate in
> https://github.com/apache/spark/pull/28205 show that floating-point ops in
> millisToDays badly impact on the performance of conversion java.sql.Date to
> Catalyst's date values. The ticket aims to replace double ops by int/long ops.
