In the end, I think we simply need guidance from the user. The user should be able to provide a hint that says \"don't deduplicate\", in which case we can avoid the `IdentityHashMap`.","issue_id":1660161939619,"origin_id":1210742814,"user_origin_id":358916,"create_time":1660141227,"update_time":1660141227,"id":1663924773580,"updated_at":"2022-09-23T09:19:33.580000Z","created_at":"2022-09-23T09:19:33.580000Z"},{"_id":"632d7a25f6ca2276484a9e93","body":"IMO conceptually we'd need a https:\/\/en.wikipedia.org\/wiki\/Bloom_filter\r\nNot keen to add a dependency though - could we check how close we get approximating it via an identity hashmap ?","issue_id":1660161939619,"origin_id":1210839635,"user_origin_id":42573,"create_time":1660144609,"update_time":1660144609,"id":1663924773583,"updated_at":"2022-09-23T09:19:33.583000Z","created_at":"2022-09-23T09:19:33.583000Z"},{"_id":"632d7a25f6ca2276484a9e94","body":">IMO conceptually we'd need a https:\/\/en.wikipedia.org\/wiki\/Bloom_filter\r\n>Not keen to add a dependency though - could we check how close we get approximating it via an identity hashmap ?\r\n\r\nYeah, either add a dependency or implement\/integrate this ourselves in hibernate-core. It's not trivial to implement this, but I think it would be worth it to add a custom implementation. Standard Bloom filters AFAIU need a fixed size, but since we keep the data around, we could grow the bit set on-demand similar to what a hash table does, but use a lot less memory (64 times memory savings i.e. for 1M elements we'd use ~2KB instead of ~1MB). Growing a bit set also consumes a lot less memory, though rehashing is still necessary.","issue_id":1660161939619,"origin_id":1211071656,"user_origin_id":358916,"create_time":1660154672,"update_time":1660154672,"id":1663924773586,"updated_at":"2022-09-23T09:19:33.585000Z","created_at":"2022-09-23T09:19:33.585000Z"}]
