Description

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 introduced a way to reduce duplication, but only GridMarshallerMappingProcessor component took advantage of it.

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.
