As per comments in Jiras this should introduce the following: * `sum` - don't promote type (e.g. `int32` to `int64`) if possible * `sum` / `mean` - should have `min_count` and return `NA` if the count of non-nulls is lower than `min_count`. * `sum` / `mean` - should short circuit when it becomes impossible for non-null count to be below `min_count`. * `mean` - should have `skipna` and `keepna` options. -- This is an automated message from the Apache Git Service.
