Binary streaming from .NET Thin Client does not create table entries visible
through SQL.
The cause seems to be an additional wrapping of the object in the Java
implementation.
* screenshot from Java debugger for STREAMING ON IIgnite OBJECT: The "val" of
the DataStreamerEntry is a "BinaryObjectImpl":

* screenshot from Java debugger for STREAMING ON IIgniteClient OBJECT: The
"val" of the DataStreamerEntry is a CacheObjectImpl that holds the
BinaryObjectImpl:

Using the Thin Client,
org.apache.ignite.internal.processors.platform.client.streamer.ClientDataStreamerReader.readCacheObject(...)
is called and wraps the object read from the input stream again, no matter if
it already is an instance of CacheObject.
When calling with Thin Client, a warning is shown:
[09:12:02,778][WARNING][data-streamer-stripe-16-#41][GridQueryProcessor]
Key-value pair is not inserted into any SQL table [cacheName=cache1,
val=CacheObjectImpl [val=Person [idHash=501908769, hash=-123912966, Age=34,
Name=Joe], hasValBytes=true]]
[09:12:02,779][WARNING][data-streamer-stripe-16-#41][GridQueryProcessor] ^--
Value type(s) are specified via CacheConfiguration.indexedTypes or
CacheConfiguration.queryEntities
[09:12:02,779][WARNING][data-streamer-stripe-16-#41][GridQueryProcessor] ^--
Make sure that same type(s) used when adding Object or BinaryObject to cache
[09:12:02,779][WARNING][data-streamer-stripe-16-#41][GridQueryProcessor] ^--
Otherwise, entries will be stored in cache, but not appear as SQL Table rows
Sample code and Java source code file with patch proposal is attached.
