4.5. Configure Expiration
In Red Hat JBoss Data Grid, expiration is configured in a manner similar to eviction.
Procedure 4.1. Configure Expiration
Add the Expiration Tag
Add the <expiration> tag to your project's <cache> tags as follows:<expiration />
Set the Expiration Lifespan
Set thelifespan
value to set the period of time (in milliseconds) an entry can remain in memory. The following is an example of this step:<expiration lifespan="1000" />
Set the Maximum Idle Time
Set the time that entries are allowed to remain idle (unused) after which they are removed (in milliseconds). The default value is-1
for unlimited time.- In Library mode, set the
maxIdle
parameter as follows:<expiration lifespan="1000" maxIdle="1000" />
- In Remote Client Server mode, set the
max-idle
as follows:<expiration lifespan="1000" max-idle="1000" />
Result
Expiration is now configured for the cache implementation.
