Re: Random2LruPageEvictionTracker causing hanging in our integration tests

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

Re: ignite node heap size

As Ilya suggested start with 2GB per server node. Then do the load testing of your cluster using basic operations you suppose to have in prod. The testing will show if you need to increase or decrease the heap size and to which degree. - Denis On Wed, Jun 3, 2020 at 3:50 AM Ilya Kasnacheev

Re: Question regarding topology

Also, In SQL query, we are having a semaphore lock where all the threads stay there and only one thread can execute the code. It's because in the code, we have jdbc connection query. And it's not thread safe. Sometimes we even get thread hanging here if we keep increasing client worker threads.

Thanks for reply. Our clients are connected in both ways one is JCache way and other is SQL way each for various caches. -> For get/put we use normal getAll() and normal putAll(). The thing is here all the threads will have their own data and the data is not shared. So no need to worry about
