Description

@asfimport

opened on Apr 25, 2022

I was trying to aggregate over time using different granularity. Usually I would use the lubridate::floor_date() , which is currently not supported for parquet datasets.

Is there any comprehensive list of supported list of currently supported {}lubridate (or dplyr{}) verbs? Maybe, it’s only my fault, but except the changelog I haven’t find any relevant information.

Later I found that the round_temporal() function is exposed to {}R{}. 
But I am struggling to find the right syntax inside a mutate statement to apply on a timestamp[us, tz=UTC] type column.

                      I was trying to aggregate over time using different granularity. Usually I would use the lubridate::floor_date() , which is currently not supported for parquet datasets.
                      Is there any comprehensive list of supported list of currently supported {}lubridate (or dplyr{}) verbs? Maybe, it’s only my fault, but except the changelog I haven’t find any relevant information.
                      Later I found that the round_temporal() function is exposed to {}R{}. 
                      
But I am struggling to find the right syntax inside a mutate statement to apply on a timestamp[us, tz=UTC] type column.
