Gang, I am facing a situation where we will end up with a large number (10s of thousands) of Associations from one entity to another, and sequential search is not really feasible. Not only will it be slow, but also very inefficient on memory, if the entire ManyAssociation list is brought in. Unfortunately, Identity is not feasible in my case, and instead a "look up by property,value" would be really useful. Since I know programmatically what value I want to lookup via, I think a "MappedAssociation" would do the trick, effectively a entity store backed hashmap with String as key and EntityRef as value. I guess that I can do this manually in the application code, but then I miss the sweet entity dereferencing mechanism that Qi4j provides, and also once we get to properly implement aggregates (if ever) I want make sure I have "Specification" support.
WDYT?
