[jboss-jira] [JBoss JIRA] (WFLY-1247) graceful shutdown

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-1247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12959764#comment-12959764 ] 

David Lloyd commented on WFLY-1247:
-----------------------------------

Internally it would be helpful to have separate services for things which may be gracefully shut down, especially if we're going for a per-deployment granularity.  By "separate services" I mean a two-phase arrangement where there is the usual service which controls the thing itself, but also a service which depends on that one (plus others as needed) which represents "accepting new sessions".  Then when graceful shutdown is initiated, this service is shut down.

This would allow an availability subsystem (as previously proposed) to easily contact e.g. a load balancer to shut down new incoming sessions when graceful shutdown is initiated, and then shut down the entire server itself when the main service is stopping, which will make this smooth in the presence of such setups.

> We need to define a clear contract between these networking services and the services that use them in order to be able to perform a graceful shutdown of remote connectors.
