> h2. Notes
> Previously upon new node joining topology grid components on each node has been collecting discovery data independently from the same components on other nodes.
> This lead to a situation when *TcpDiscoveryNodeAddedMessage* and *TcpDiscoveryNodeAddFinishedMessage* carried a lot of duplicated data wasting network traffic.
> Refactoring done within [IGNITE-4157|https://issues.apache.org/jira/browse/IGNITE-4157] introduced a way to reduce duplication, but only *GridMarshallerMappingProcessor* component took advantage of it.
> h2. Acceptance Criteria
> *  Identify all components needed to be optimized in terms of discovery data collection.
> * Refactor them to reduce duplication of discovery data.
> * Remove *filterDuplicatedData* method as obsolete from *DiscoveryDataContainer* when refactoring is done.
