Hi Mahesh, The defined anonymous class( IgniteBiFunction) will be executed on the server side, so it should be deployed there first, you can do this manually, by extracting the class to distinct class, compile to jar and add to libs folder on the server side. Or you need to enable peer class loading: https://apacheignite.readme.io/docs/zero-deployment
