Hi, It seems to me that there are two questions in this post: 1) How to store cross-referencing data in an IgniteCache? 2) How to extract data from server based on some complex filter?
First, on the cross-references. To store a reference to another entity, which is stored as a separate entry in the cache, one would usually store that referenced value's key. So that neither TestItem nor TestList aggregate the other but they have the keys and can obtain needed objects from the cache. To avoid querying the cache each time you need to access TestList from a TestItem you could do that during the TestItem's construction (e.g. in WriteBinary). On executing filters on server: ScanQuery seems appropriate, and you usually can declare a field with InstanceResourceAttribute to have an instance of Ignite injected into it. However, I'm not sure if ICacheEntryFilter is being processed like that and can't check that right now. Could you please try that? Alternatively, you could call use ICompute.broadcast to get execute a closure on all nodes and return a result. To execute filter efficiently, make sure that your data is collocated and that you're performing local queries from the filter, or you might end up quering other nodes to filter local data and creating a lot of load this way.
