= Setting Up Persistent Storage
{brandname} can persist in-memory data to external storage, giving you
additional capabilities to manage your data such as:

Durability::
Adding cache stores allows you to persist data to non-volatile storage so it
survives restarts.
Write-through caching::
Configuring {brandname} as a caching layer in front of persistent storage
simplifies data access for applications because {brandname} handles all
interactions with the external storage.
Data overflow::
Using eviction and passivation techniques ensures that {brandname} keeps only
frequently used data in-memory and writes older entries to persistent storage.
