Valentin Kulichenko commented on IGNITE-950:
--------------------------------------------

One of the users pointed out an issue with indexing and custom class loading (I 
think the issue exists for peer-deployment as well): 
http://apache-ignite-users.70518.x6.nabble.com/Dynamic-classes-in-IgniteCache-td705.html

I believe it should be fixed in the scope of this ticket.

>             Project: Ignite
>          Issue Type: Improvement
>          Components: general
>    Affects Versions: sprint-5
>            Reporter: Denis Magda
>            Assignee: Alexey Goncharuk
>             Fix For: sprint-7
>
>
> When field names of an object are used in SQL, text or other kind of queries, 
> object, that owns a field, is fully deserialized.
> This is bad from performance perspective. 
> The task is to support peer field deserialization by looking it up in a 
> marshalled byte array and unmarshalling it from a concrete offset with 
> OptimizedMarshaller later.
