After some profiling we found out that post processing of records and vertices takes are lot of resources in layer above the storage, to improve such situation following steps are proposed:

Caddy needs a cache middleware.
I'll be working on something basic this week. Probably just a basic LRU replacement algorithm and a configurable expiration time. In fact, if the gain is significant i…

I noticed that concurrentlinkedhashmap originally planned on having LIRS eviction for v2.x according to the google code page [1].
Is this still planned for caffeine the successor to concurrentlinkedh…

Right now cache can hold partition in its entirety ("complete") or not at all. This is problematic for workloads creating large partitions:
- Reading whole partition may result in large read amplifica…

I observed a very high false positive rate with the current implementation of [BloomFilter](https://github.com/ben-manes/caffeine/blob/master/simulator/src/main/java/com/github/benmanes/caffeine/cache…

We're currently using the same `Ring` implementation that the ZODB pickle cache uses to manage entries in the shared memory cache. This implementation can only be used as a strict LRU based cache: new…

This may not be a bug, but, it is a difference between Guava and Caffeine. Basically, the most recent entry put into a cache appears to sometimes be the first one expired. Our actual use case is put…

We have a use case where we want to set the createTime on which eviction should be based, rather than always using the time the entry was created. Extending it further, I think it would be nice to hav…

Hi @ben-manes
Have you consider a cache for long keys similar to https://github.com/JCTools/JCTools/blob/master/jctools-experimental/src/main/java/org/jctools/maps/NonBlockingHashMapLong.java
It got…

When trying to use caffeine in an asynchronous server I ran into a deadlock that caused requests to stop processing. I believe this would happen in a synchronous server too if it was using async refre…
