Evgeny Stanilovsky updated IGNITE-18897:
----------------------------------------
Fix Version/s: 3.2
(was: 3.1)
> TopologyService must cache local ClusterNode.
> ---------------------------------------------
>
> Key: IGNITE-18897
> URL: https://issues.apache.org/jira/browse/IGNITE-18897
> Project: Ignite
> Issue Type: Improvement
> Components: networking
> Reporter: Andrey Mashenkov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.2
>
>
> As of now, ScaleCudeTopologyService.localMember() creates a new ClusterNode
> instance on each call.
> This method used widely in the project, so it make sense to avoid unwanted
> instantiations.
> Moreover, every message is checked if it is sent to a local node or not, and
> uses topologyService.localMember().
> We can get faster equality checks if local ClusterNode will be a single
> object.
> Let's cache ClusterNode object for the local node, and maybe do the same for
> all objects using `intern()` ideas.
> See how it is is done in RelDataTypeFactoryImpl.DATATYPE_CACHE in Calcite (it
> uses Interners.newWeakInterner() from Guava)
