Thanks for your input, Val. Now that I am back at the office, I can see that I am already using a Factory:
<pre> igniteConfiguration.setCacheStoreFactory(new FactoryBuilder.SingletonFactory<>(this.cacheMissHandler)); </pre> Obviously the problem is the SingletonFactory, as it will pass the instance around the topology, and any client that doesn't have that class will throw this de-serialization exception. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/CacheStore-being-serialized-to-client-tp1931p1941.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
