Thanks Ilya. I tried all your suggestions and they work as expected. I'll close the bug.
WRT cache groups, what's the rule of thumb with using cache groups? I read https://apacheignite.readme.io/docs/cache-groups, but I'm not sure on the approach I should take. Should I simply stay away from cache groups until I need them? Or should I use them from the start. What is your suggestion? thanks. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
