Description

Azure does not have a watch/subscribe functionality in Azure storage. Therefore, any change in the list of processors in the system will be detected by monitoring each processor's heartbeats. A change in the job model as well as rebalancing state will also require polling to Azure Storage Services. These classes will implement the basic notification listener implementation required for the same.
