---------------------------------------------
Summary: Introducing Maintenance state to Topology
Key: STRATOS-454
URL: https://issues.apache.org/jira/browse/STRATOS-454
Project: Stratos
Issue Type: Improvement
Components: Cartridge Agent, Cloud Controller, Eventing
Affects Versions: 4.0.0 M7
Reporter: Reka Thirunavukkarasu
Assignee: Reka Thirunavukkarasu
Fix For: 4.0.0 Alpha
In the graceful shutdown, we keep the member as active until it receives
ReadyToShutdown event. In between these state changes, member will become
unavailable. So the LB needs to aware of that, in order to avoid sending
requests to a member which is going to graceful shutdown. I think that if we
introduce another state say Maintenance in the Topology, before the actual shut
down of the application inside the member takes place, then the LB will act
upon the Maintenance state and remove the member from the active members list.
