<title>Server Cache</title>
|
|
<para>
|
|
By default, Keycloak caches realm metadata and users. There are two separate caches, one for realm metadata
|
|
(realm, application, client, roles, etc...) and one for users. These caches greatly improves the performance of the server.

<para>
|
|
The realm and user caches can be cleared through the management console. To
|
|
disable the realm or user cache, you must edit the <literal>keycloak-server.json</literal> file
|
|
in your distribution. Here's what the config looks like initially.

<title>Clear Caches</title>
|
|
<para>
|
|
To clear the realm or user cache, go to the Keycloak admin console Realm Settings->Cache Config page. Disable the cache
|
|
you want. This will cause the cache to be cleared.
