>
> A thin client sends putAllConflict/removeAllConflict with the keepBinary 
> flag, but since IGNITE-28348 the server
> handles them without it: ClientCacheRequest#internalCache obtains the 
> internal cache through
> IgniteCacheProxy#internalProxy(), which drops the withKeepBinary() applied to 
> the public proxy.
> Because of that, the primary node deserializes the values when 
> CacheVersionConflictResolver compares them. On a CDC
> destination cluster fed by a thin client streamer the value classes are 
> usually not deployed, so the resolver fails
> with BinaryInvalidTypeException, the transaction commit ends with a heuristic 
> failure and the failure handler stops
> the node.
