Collector

Caching

Prometheus collector offers a caching mechanism for faster restart with different backends defined by the cache spec:

Cache spec	Description
file://path/to/cache/	Use local filesystem to cache data (use PVC inside Kubernetes!)
azblob://{storageAccountName}.blob.core.windows.net/{containerName}/{optionalPath}	Use Azure StorageAccount to save cache data (with optional sub path)
k8scm://{namespace}/{configMapName}	Use Kubernetes ConfigMap to save cache data
