In general `DeclarativeAggregate` should be faster than `ImperativeAggregate`. Based on [this](https://github.com/apache/spark/pull/10786/files#r50038294) benchmark the `CentralMomentAgg` was migrated from imperative to declarative. So I assume, that for primitive types the `first` would become slower because of this change. -- This is an automated message from the Apache Git Service.
