kandi X-RAY | concurrentlinkedhashmap Summary

concurrentlinkedhashmap is a Java library typically used in Server, Caching applications. concurrentlinkedhashmap has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Caffeine is the Java 8 successor to ConcurrentLinkedHashMap and Guava's cache. Projects should prefer Caffeine and migrate when requiring JDK8 or higher. The previous caching projects are supported in maintenance mode. A high performance version of java.util.LinkedHashMap for use as a software cache. The project was migrated from its old website on Google Code.

QUESTION

Can you still use a ConcurrentLinkedHashMap with Caffeine?

Asked 2022-Mar-21 at 19:45

Caffeine provides a great alternative to Guava's caching library, but can you still use just the ConcurrentLinkedHashMap class itself, or a Cache the implements concurrent, in-order iteration? It does not appear in Caffeine anymore that I can see, although I'm sure its using something similar under the hood.

I have tested the Caffeine Cache and it does not iterate over the elements in order of insertion, and I don't see any options on the Caffeine builder that would make me thing this feature still exists. But maybe I'm missing something.

Any ideas?

ConcurrentLinkedHashMap offered access-order iteration via the ascending and descending snapshots. This was useful for cases like persisting the hottest entries for a warm server restart. Otherwise views and iterators were in encounter order by the underlying ConcurrentHashMap.

Caffeine offers snapshots by in the eviction policy's hottest/coldest order and the expiration policy's youngest/oldest order. See Cache.policy().

Insertion-order is not that difficult to implement because writes are rare, exclusive, and items are not being shifted around frequently. The simplest approach is to use a Map computation to maintain a secondary data structure. If you want that in addition to the cache then Caffeine's asMap() view offers atomic versions. This way you can have fast random access reads via a ConcurrentHashMap and ordered iterations for a background process.

I am using org.apache.cayenne.util.concurrentlinkedhashmap and setting cache capacity by using maximumWeightedCpacity(3000) method once cache reached to its threshold limit it starts evicting the old entries. I need that entries which is getting evicted. How Can I get those entries using listener?

micronaut-elasticsearch is not a part of grails-bom. So you have to specify a version of the dependency.

I think it is sigar-lib that cassandra uses that is causing the problem (especially on the recent JDK8).

It is not necessary to run cassandra, so you can comment out this line from cassandra-env.ps1 in conf directory: https://github.com/apache/cassandra/blob/cassandra-3.11.7/conf/cassandra-env.ps1#L357
