How to cache session with IBM WebSphere Liberty on AWS?

Question

I would like to use AWS Elasticache for Liberty’s session caching, but it looks like Liberty's sessionCache-1.0 feature can only be used with JCache compliant storage. (like Hazelcast, Infinispan, etc...).

so please let me confirm.

• Is this correct that it is impossible to use Liberty’s feature (sessionCache-1.0) with AWS Elasticache?
• If so, do I need to write custom code for session caching in my application?

If you have any suggestions on how to realize session caching in Liberty, I would appreciate it.

Answer 1

Eventualy I could configure the sessionCache-1.0 feature with redisson.
Followings are the configuration flagment for ElastiCache Redis (Cluster Mode Disabled).

server.xml

・・・
    <!-- JCache Library -->
    <library id="jCacheVendorLib">
        <fileset dir="${shared.resource.dir}/redisson" includes="*.jar"/>
    </library>

    <!-- Session Replication -->
    <httpSessionCache libraryRef="jCacheVendorLib" uri="file:${shared.resource.dir}/redisson/redisson-jcache.yaml"/>
・・・

redisson-jcache.yaml
