== Server Cache Configuration
|
|
|
|
{{book.project.name}} has two types of caches. One type of cache sits in front of the database to decrease load on the DB
|
|
and to increase overall response times by keeping data in memory. Realm, client, role, and user metadata is kept in this type of cache.
|
|
This cache is an invalidation cache. Invalidation caches do not use replication.
|
|
Instead, they only keep copies locally and if the entry is updated an invalidation message is sent to the rest of the cluster
|
|
and the entry is evicted. This greatly reduces network traffic, makes things efficient, and avoids transmitting sensitive
|
|
metadata over the ire.
|
|
|
|
The second type of cache handles managing user sessions, offline tokens, and keeping track of login failures so that the
|
|
server can detect password phishing and other attacks. The data held in these caches is temporary, in memory only,
|
|
but is possibly replicated across the cluster.
|
|
|
|
This chapter discusses some configuration options for these caches for both clustered a non-clustered deployments.
|
|
|
|
Note: More advanced configuration of these caches can be found in link:{{book.caching.admindoc.link}}[{{book.caching.admindoc.name}}]
