Subject [jira] [Commented] (IGNITE-2475) DateTime support and functions
Date Tue, 02 Feb 2016 16:48:39 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-2475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15128532#comment-15128532

Pavel Tupitsyn commented on IGNITE-2475:

* 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).
