Storage-System Service

Purpose and description to be added

Caching

The storage-system service caches file metadata via the configured store in STORAGE_SYSTEM_CACHE_STORE. Possible stores are:

• memory: Basic in-memory store and the default.
• redis: Stores metadata in a configured Redis cluster.
• redis-sentinel: Stores metadata in a configured Redis Sentinel cluster.
• etcd: Stores metadata in a configured etcd cluster.
• nats-js: Stores metadata using the key-value-store feature of nats jetstream
• noop: Stores nothing. Useful for testing. Not recommended in productive enviroments.

1. Note that in-memory stores are by nature not reboot persistent.
2. Though usually not necessary, a database name can be configured for event stores if the event store supports this. Generally not applicapable for stores of type in-memory, redis and redis-sentinel. These settings are blank by default which means that the standard settings of the configured store applies.
3. The storage-system service can be scaled if not using in-memory stores and the stores are configured identically over all instances.
4. When using redis-sentinel, the Redis master to use is configured via STORAGE_SYSTEM_CACHE_NODES in the form of <sentinel-host>:<sentinel-port>/<redis-master> like 10.10.0.200:26379/mymaster.
