Pavel Tupitsyn commented on IGNITE-2475:
----------------------------------------
Issues:
* Default serialization writes DateTime as a binary object. It can be used in
queries (retrieval works properly), but it does not work in equality and other
comparisons. User has to use custom serialization (IBinarizable).
* [QueryField] does not map DateTime fields to Timestamp (because this won't
work with default serialization). Possible solution is to introduce
[QueryFieldDateTime] which will force Timestamp mapping. This will require
custom serialization, of course.
* When passing DateTime as a query argument, it will be always written as a
binary wrapper. We need a custom way of writing arguments (like
QueryBase.ArgumentWriter).
