Generally, use weak references to persistent instances so they can be garbage collected when the user no longer holds a strong reference to them. Unflushed dirty instances need to be referenced strongly so they are not garbage collected. So at flush time, move the flushed dirty instances from a strong-reference map to a weak-reference map (key = oid, value = weak-reference object).

without breaking JDO contract and capable to handle load, any tips?

Thanks

In case of huge amount of objects loaded /persisted, the flush method is for this purpose. I wonder how the cache/state management can be implemented
