It is not applicable because it will require too much effort to convert the rest of the system for ACTIVE/ACTIVE set-up. On Thu, Apr 13, 2017 at 5:10 PM vkulichenko wrote: > Why not create two equal C++ nodes and use both of them? You will give you > data

Re: How do I provide AffinityFunction.BackupFilter when mainly using C++ bindings

Why not create two equal C++ nodes and use both of them? You will give you data redundancy and load balancing, without any custom affinity functions. Your model seems to be worse and also requires more effort. I would recommend to use abilities provided by Ignite out of the box. -Val -- View

Charles, In your case, you have many caches registered on server nodes (debug shows me about 80) which are to be created on the client. These caches don't participate in common activities, instead they are used to prepare execution plan. As for now, a separate request is sent to remote nodes for
