About Metric Store
Metric Store provides a persistent storage layer for metrics sent through the Loggregator subsystem. It is multi-tenant-aware, because the auth proxy ensures that you only have access to metrics from your apps, and easy to query because it’s compatible with PromQL. It also has the powerful InfluxDB storage engine, which has built-in compression and a memory-efficient series index.
- Multi-tenant aware: Application Developers have access to their own metrics.
- Ubiquitous Query Language: Metric Store is compatible with PromQL and Prometheus API Query endpoints.
- Powerful Storage Engine: The InfluxDB storage engine has built-in compression and a memory-efficient series index.
Metric Store offers multi-node deployments, data replication, hinted handoff, and load balancing in a highly-available configuration.
The only officially supported use case for the Metric Store product is as the backing Time Series Database for App Metrics v2.2 and the TAS v2.9 and later Apps Manager. Use cases outside of these bounds have no guarantee of continued support or availability.

Limitations
Metric Store has the following limitations:
- Horizontally scaling Metric Store currently results in data loss. Vertical scaling is recommended at this time.
- Platforms are ever changing and we cannot guarantee metric stability. Using Metric Store through products such as App Metrics or Learning about Apps Manager are supported use cases. When using Metric Store manually through endpoints, you must be aware of changes through Platform upgrades.
