> Discovery data distribution process optimization
> ------------------------------------------------
>
> Key: IGNITE-4435
> URL: https://issues.apache.org/jira/browse/IGNITE-4435
> Project: Ignite
> Issue Type: Improvement
> Components: general
> Reporter: Sergey Chugunov
> Fix For: 2.0
>
>
> 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.
