> Key: MESOS-3165
> URL: https://issues.apache.org/jira/browse/MESOS-3165
> Project: Mesos
> Issue Type: Task
> Components: master, replicated log

>
> To persist quotas across failovers, the Master should save them in the
> registry. To support this, we shall:
> * Introduce a Quota state variable in registry.proto;
> * Extend the Operation interface so that it supports a ‘Quota’ accumulator
> (see src/master/registrar.hpp);
> * Introduce AddQuota / RemoveQuota operations;
> * Recover quotas from the registry on failover to the Master’s
> internal::master::Role struct;
> * Extend RegistrarTest with quota-specific tests.
> NOTE: Registry variable can be rather big for production clusters (see
> MESOS-2075). While it should be fine for MVP to add quota information to
> registry, we should consider storing Quota separately, as this does not need
> to be in sync with slaves update. However, currently adding more variable is
> not supported by the registrar.
