Persistent and ephemeral storage

For each node in the cluster, you can configure both a persistent storage and an ephemeral storage path.

  • Persistent storage is mandatory; it is used by the cluster to store information that needs to persist even if a shard or a node fails, e.g logs, configurations, files. For example, if you choose any type of persistence for a database, then the persistence information is stored in this location.
  • Ephemeral storage is optional. If defined, it is used by the cluster to store information that does not need to persist. This aids in optimization and helps to reduce the load on the persistent storage.

Critical: DO NOT confuse persistent or ephemeral storage on this page with Redis persistence or AWS ephemeral drives used in other areas of Redis Enterprise Pack.
