How to integrate Apache Ignite with Cassandra as third party persistence? - kubernetes

Question

I tried out below configurations but I get ClassNotFoundException for org.apache.ignite.cache.store.cassandra.CassandraCacheStoreFactory. I am using docker image of apache ignite to achieve the same and its version is 2.9.1.

Can anyone help me out on this? Any sort of sample github project or blog reference will also work out for me.
