Dmitry Karachentsev commented on IGNITE-3154:
---------------------------------------------

Vladimir, I don't see the correct way for using lazy metadata loading, because it may be changed in runtime and some code depends on this behavior (e.g. org.gridgain.internal.processors.dr.DrMetadataTest#testBinaryMetadataPropagation())

> *Problem*
> Currently creation of binary field is performed as follows: {{BinaryObject.type().field(...)}}. Call to {{BinaryObject.type()}} is pretty expensive as it requires metadata lookup. Interesting thing is that subsequent call to {{BinaryType.field()}} doesn't require metadata at all. 
> *Solution*
> Implement lazy metadata load for this case.
