> Re-use Literal objects when replacing timestamps in the ComputeCurrentTime

> Key: SPARK-45660
> URL: https://issues.apache.org/jira/browse/SPARK-45660
> Project: Spark
> Issue Type: Improvement
> Components: Optimizer
> Affects Versions: 3.5.0
> Reporter: Jan-Ole Sasse
> Priority: Minor
> Labels: pull-request-available
>
> The ComputeCurrentTime optimizer rule does produce unique timestamp Literals
> for current time expressions of a query. For CurrentDate and LocalTimestamp
> objects only the literal objects are not re-used though, but equal objects
> are created for each instance. This can cost unnecessary much memory in case
> there are many such Literal objects.
