RE: Re: Ignite.Net Read through approach - error : could not create .Net cachestore
Sudhir, If I configure a cacheStore for a clientNode, then using 2.7.6 it becomes initialized twice, for both server and a client.Whereas I checked the same scenario against the master-branch and only a single cache store had created. Also, I have found the IGNITE-1903 that may fix the issue for the master. > What I am trying is call get operation on a key in cache for 1st time from client node as per my requirements. i.e. server node don't >have that key yet. Is this possible or correct??? I think yes because it worked without any issues when I used thin client instead of >normal client node. All cache query operations are routed to the server. Local cacheStore could be required for some transactional scenarios as well as for near caching. So, I would suggest you configure a cacheStore only for server nodes.

What I am trying is call get operation on a key in cache for 1st time from client node as per my requirements. i.e. server node don't have that key yet. Is this possible or correct??? I think yes because it worked without any issues when I used thin client instead of normal client node.Server & client node communication works fine (i.e. client retrieves key value stored from cache etc) without cachestore enabled on server. But it throws that exception when cachestore is enabled.

RE: Re: Ignite.Net Read through approach - error : could not create .Net cachestore
Sudhir, Can you share a stacktrace? It’s difficult to locate the problem without the details.According to source code, the exception is thrown when .NET side is unable to create a CacheStore instance.Since you have configured a factory, please, check that it returns a correct instance and the class is present for required nodes.
