---------------------------------------
Assignee: Pavel Kovalenko
> Reduce time on processing CustomDiscoveryMessage by discovery message worker
> ----------------------------------------------------------------------------
>
> Key: IGNITE-9398
> URL: https://issues.apache.org/jira/browse/IGNITE-9398
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.4, 2.5, 2.6
> Reporter: Pavel Kovalenko
> Assignee: Pavel Kovalenko
> Priority: Major
> Fix For: 2.7
>
>
> Processing discovery CustomMessage may take significant values of time
> (0.5-0.7 seconds) before sending to next node in the topology. This
> significantly accumulates the total time of PME if topology has multiple
> nodes.
> Let X = time of processing discovery message by discovery-msg-worker on each
> node before sending to next node.
> Let N = number of nodes in the topology.
> Then the minimal total time of exchange will be:
> T = N * X
> We shouldn't make heavy actions when process discovery message. Best solution
> will be separated thread that will do it, while discovery-msg-worker will
> just pass a message to that thread and send a message immediately to another
> node in topology.
> This affects both TcpDiscoverySpi and ZkDiscoverySpi.
