Enabling Faster Missing Cell Recovery #11

Closed onsi closed 9 years ago

onsi commented 9 years ago

Our worst-case time between Cell goes down => Diego restarts missing instances is ~1 minute. This proposal reduces this time to ~5 seconds.

This makes for a better SLA and better demos.

Amit made a comment: Why remove it? If a watch-event gets missed, what eventually brings about consistency except for the convergence loop? Seems like we'd still want to keep this.

That got dropped.

I totally agree. Fixing the proposal.
