# Storages

<AccordionGroup>
  <Accordion title="What are Storages used for?">
    Storages persist data between integration runs. The most common use cases are delta filtering (only processing new or changed records), pagination tracking, caching, and cross-system ID mapping.
  </Accordion>

  <Accordion title="My Storage is growing very large. What should I do?">
    Enable pruning on the Storage to automatically delete entities older than a defined threshold. Left unmanaged, a full database will make your Alumio environment unavailable.
