Chapter 14. Install Time-Series-Database-as-a-Service

The storage driver is responsible for storing measures of created metrics. It receives timestamps and values and computes aggregations according to the defined archive policies.

The indexer driver is responsible for storing the index of all resources, along with their types and their properties. Time-Series-as-a-Service only knows resource types from the OpenStack project, but also provides a generic type so you can create basic resources and handle the resource properties yourself. The indexer is also responsible for linking resources with metrics.
