Description
Considering the code of str_to_date and date_format, now in BE we deal with the input data line by line. And for one cell we parse the format per %. Actually for some usual formats(like "%Y-%m-%d", "%H:%i:%s" and so on) we can use an individual function to directly set the result time or string. And do not need to parse the format string. Furthermore, maybe we can use SIMD to accelerate this.
Use case
detect some usual format string for str_to_date and date_format. then use a new function to directly deal with the input column to get the result.
