Re: Could not create .NET CacheStore

e they can access this cache. We are planning to change that in future releases, so that Cache Store is only started if it is needed. Also, cache configuration will be discarded if cache exists in cluster, this means, only the original cache settings will be used. Regards, -- Ilya Kasnacheev

Re: Client Vs Server Configuration

Hello! I think that CacheLoader will be executed on server nodes. If you need data loading to happen on client node, better use Data Streamer. Otherwise, sounds OK, location of cache configurations is not important once caches are started. Regards, -- Ilya Kasnacheev вт, 21 янв. 2020 г. в 02

Re: Use custom Data Region or custom Cache for IgniteAtomicReference - Ignite 2.3

Hello again! I guess that maybe you have to specify a default data region configuration here, and not just rely on default configuration for default data region. I also think this is a bug :) Regards, -- Ilya Kasnacheev пн, 20 янв. 2020 г. в 20:16, Ilya Kasnacheev : > Hello! > >
