Prevent flushing data during update

[nsagnett]

Hello,

I want to know if it's possible to prevent flush data when application have to restart or be updated, because we have the case where some consumers are inactive at the update time and there are not restored on HTTP calls after update.

Can you provide method or configuration to have a temporary storage data like external caching or anything lese?

Don't hesitate if the request miss clarity :)

Many thanks!
