------------------------------------------
Summary: Persist and recover quota to/from Registry
Key: MESOS-3165
URL: https://issues.apache.org/jira/browse/MESOS-3165
Project: Mesos
Issue Type: Task
Components: master, replicated log
Reporter: Alexander Rukletsov
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.
