Vladimir Steshin updated IGNITE-13014:
--------------------------------------
Attachment: WorstCase_log.log
> Remove double checking of node availability.
> ---------------------------------------------
>
> Key: IGNITE-13014
> URL: https://issues.apache.org/jira/browse/IGNITE-13014
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladimir Steshin
> Assignee: Vladimir Steshin
> Priority: Major
> Labels: iep-45
> Attachments: WorstCase_log.log, WostCase.txt
>
>
> Proposal:
> Do not check failed node second time. Double node checking prolongs node
> failure detection and gives no additional benefits. There are mesh and
> hardcoded values in this routine.
> For the present, we have double checking of node availability. Let's imagine
> node 2 doesn't answer any more. Node 1 becomes unable to ping node 2 and asks
> Node 3 to establish permanent connection instead of node 2. Node 3 may try to
> check node 2 too. Or may not.
> Possible long detection of node failure up to ServerImpl.CON_CHECK_INTERVAL +
> 2 * IgniteConfiguretion.failureDetectionTimeout + 300ms. See ‘WostCase.txt’
