Nikolay Izhikov updated IGNITE-27775:
-------------------------------------
    Description: 
Currently, many typed collections and array written by IDTO autogenerated code 
write in not efficient way:

{code:java}
IDTO {
    UUID[] nodeIds;
}

IDTOSerializer {
    write() {
         U.writeArray(out, obj.nodeIds);
    }
}

U {
    writeArray() {
            for (T t : arr)
                out.writeObject(t);
    }
}
{code}

We can do it more efficiently if generate code based on generic collection 
argument. For example:

{code:java}
IDTOSerializer {
    write() {
            for (UUID t : obj.nodeIds)
                U.writeUUID(t);
    }
}
{code}
