The use of with virtual threads causes with Caffeine local (sync) cache causes the pinning of the "carrier" thread due to the internal use ofConcurrentHashMap. to prevent the pinning of the carrier thread, and resulting, performance degradation a workaround consists using the "async" version o...
This mutex could be mostly avoided by using a concurrent hash map. AtomTable Status: After exploring this for a while, there's a problem. It seems like what AtomTable/Typeindex really requires is a concurrent unordered multimap, with thread-safe erasure. There are 5 or 6 packages that prov...
newKeySet(), which allows you to create a concurrent hash set backed by a concurrent hash map. If you remember, whenever you get keys from the map, they are returned in a

We can create a concurrent HashSet using two methods. We use two ways to create a concurrent HashSet, namely using the KeySet and the newKeySet method. 1. Using newKeySet The newKeySet method returns the supported type of concurrent HashMap, where the value of the method is Boolean. We ...
ConcurrentMap<String, Set<X>> map =newConcurrentHashMap<String, Set<X>>();//... map.putIfAbsent(name, new HashSet<X>()); map.get(name).add(Y); Readability wise this is great but it does require creating a new HashSet every time even if it is already in the map. I could writ...
