In addition to Infinispan caches, offline sessions are stored in a database which means they will be available even after server restart.
|
|
|
|
|
By default, the offline sessions are not preloaded from the database into the Infinispan caches during the server startup, because this

approach has a drawback if there are many offline sessions to be preloaded. It can significantly slow down the server startup time.
|
|
|
|
|
Therefore, the offline sessions are lazily fetched from the database by default.

However, {project_name} can be configured to preload the offline sessions from the database into the Infinispan caches during the server startup.
|

|
|
|
It can be achieved by setting `preloadOfflineSessionsFromDatabase` property in the `userSessions` SPI to `true`.
