Re: Recommendation: running Cassandra in containers

The use of Mesos in production for cassandra was a failure due to the
inability to reserve network bandwidth as Mesos can only allocate cpu and
memory profiles to a task. So, assuming you are either running on
dedicated/manually controlled VM's, or are no running a product/meaningful
data storage footprint, your questions are relevant. Otherwise Mesos is not
a viable solution. Note this same issue hit me at several clients with
jenkens CI workloads as well. Look at K8S for these contra-Mesos scenarios.

"When I finish a project for a client, I have ... learned their issues with
life, their personal secrets, I have come to care about them.
Once the project is over, I lose them as if I lost family. For the client,
however, they’ve just dismissed a service worker." ...
