Caching¶

Nautobot supports database query caching using django-cacheops and Redis. When a query is made, the results are cached in Redis for a short period of time, as defined by the CACHEOPS_DEFAULTS parameter (15 minutes by default). Within that time, all recurrences of that specific query will return the pre-fetched results from the cache.

If a change is made to any of the objects returned by the query within that time, or if the timeout expires, the results are automatically invalidated and the next request for those results will be sent to the database.

Invalidating Cached Data¶

Although caching is performed automatically and rarely requires administrative intervention, Nautobot provides the invalidate management command to force invalidation of cached results. This command can reference a specific object my its type and numeric ID:

$ nautobot-server invalidate dcim.Device.34

Alternatively, it can also delete all cached results for an object type:

$ nautobot-server invalidate dcim.Device

Finally, calling it with the all argument will force invalidation of the entire cache database:

$ nautobot-server invalidate all
