Data Store: Capacity Management

[rtamalin]

The client data store should enforce a max storage capacity, discarding older telemetry data items to make space as needed when new telemetry data items are being added.

The storage capacity should be dictated by the following:

• configuration settings
• available storage capacity on the storage solution hosting the data store

Data Store storage management could be triggered for the following scenarios:

• New telemetry generated by a provider - create space for new telemetry
  • make room by discarding older telemetry
• Periodic Bundling & Reporting - reduce consumption if it exceeds configured max
  • attempt to free up space by submitting telemetry
  • discard older telemetry until below target
