[jira] [Updated] (IGNITE-4296) Optimize GridDhtPartitionsSingleMessage processing

["Semen Boikov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-4296?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Semen Boikov updated IGNITE-4296:
---------------------------------
    Description: 
These optimizations are possible:
- now on exchange GridDhtPartitionsSingleMessage is processed inside exchange future exclusive lock
- GridDhtPartitionTopology.update always creates copies of node2part, part2node maps
- it is possible for joning node do not send GridDhtPartitionsSingleMessage since we know in advance it does not have any data
- method GridDhtPartitionTopology.update returns map copy which is not actually used
