Subject Re: Dedup mesos agent status updates at framework
Date Mon, 29 Oct 2018 01:49:37 GMT
Hi Varun,

What problem are you trying to solve precisely? There seems to be an
implication that the duplicate acknowledgements are expensive. They should
be low cost, so that's rather surprising. Do you have any data related to
this?

You can also tune the backoff rate on the agents, if the defaults are too
noisy in your setup.
