Hi Slava Koptilin Thanks for your email.
Cache configuration used at time of cache creation in C# code. Please suggest me if any configuration changes required in cache level or grid level CacheConfiguration.CopyOnRead=false CacheConfiguration.EagerTtl=true CacheConfiguration.CacheMode = CacheMode.Partitioned CacheConfiguration.Backups = 1 *Client node xml bean* <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans";
