> Reporter: Vsevolod Ostapenko
> Priority: Major
> Fix For: v2.5.0
>
>
> In a multitude of existing enterprise applications partitioning is done on a
> single column that fuse date and time into a single value (string, integer or
> big integer). Typical formats are YYYYMMDDHHMM or YYYYMMDDHHMMSS (e.g.
> 201801181621 and 20180118154734).
> Such representation is human readable and provides natural sorting of the
> date/time values.
> Lack of support for such date/time representation requires some ugly
> workarounds, like creating views that split date and time into separate
> columns or data copying into tables with different partitioning scheme, none
> of which is a particularly good solution.
> More over, using views approach on Hive causes severe performance issues, due
> to inability of Hive optimizer correctly analyze filtering conditions
> auto-generated by Kylin during the flat table build step.
