Caching Systems

Below are diagrams of Caching systems within Decisions.

v7 and Below (Multi-server)

The Decisions application server has a local cache that is different than the database. Using the various Cache steps affect this cache. However if there are multiple servers in a cluster, each of those servers has its own cache. Each server keeps separate versions of objects in cache local to them. Those servers send events to each other to clear and refresh those objects from cache.

v8 and Below (Single Server)

The Decisions application server has a local cache that is different than the database. Using the various Cache steps affect this cache.

v8.3 to Current

As of v8.3 caching is handled by Redis-Cache and not locally per server as in prior versions. Local cache is still available, but it is not the default location.
