> I am working on an engine to handle timeseries data. Unsurprisingly for such a system, values of timestamp type feature prominently and we need basic support for them in DataFusion.
> Initially, we want to use DataFusion with predicates such as '=', '<', '>', etc on timestamp columns and timestamp literals. For example, finding all rows in a dataset that fall within a certain timestamp range.
> Here is a document with a more formal proposal: https://docs.google.com/document/d/18O9YPRyJ3u7-58J02NtNVYb6TDWBzi3mIQC58VhwxUk/edit#
