Glad you liked it!

Not at the moment, no. Though it could, theoretically, be used within groupcache. We'll look into that as it has been brought up a few times now.

We could definitely look into adding a config flag for that. I'd love to know: in what situations would lossless Sets be important to you? We already have guaranteed updates, so the only Sets that are dropped are new items.

Also, if we guarantee that every Set is accepted, it goes against the idea that the Estimate of the incoming key must be higher than the Estimate of the key getting evicted.

Of course, one way to ensure every key goes in is to have a cache of infinite MaxCost. But, that’s an orthogonal idea, I guess.

Ahh! I missed that only new items are dropped, while updates are always accepted. That avoids the “umm, I have stale data” issue. That was my main worry!
