go-concurrentMap is a concurrent Map implement, it is ported from java.util.ConcurrentHashMap. Current version: 1.0 Beta Quick start Put, Remove, Replace and Clear methods m:=concurrent.NewConcurrentMap()previou,err:=m.Put(1,10)//return nil, nilpreviou,err=m.PutIfAbsent(1,20)//return ...
Equivalent performance toConcurrentHashMapunder load. Can bound by the size of the values (e.g. Multimap cache). Can notify a listener when an entry is evicted. See thetutorialfor examples of using this library. Status Released v1.4.2withLeast-Recently-Usedpage replacement policy. ...

5.ConcurrentHashMap 锁分段机制 ConcurrentHashMap同步容器类是java5增加的一种线程安全的哈希表。对于多线程操作,介于HashMap和HashTable之间。内部采用了“锁分段”机制,替换了HashTable的独占锁,进而提高了性能。 我们知道HashMap与HashTable的区别在线程安全与线程不安全,HashTable采用了独占锁的方式,当多个线程同时...

1. ConcurrentHashMap 1.7 1. 存储结构 Java 7 中 ConcurrentHashMap 的存储结构如上图,ConcurrnetHashMap 由很多个 Segment 组合,而每一个 Segment 是一个类似于 HashMap 的结构,所以每一个 HashMap 的内部可以进行扩容。但是 Segment 的个数一旦初始化就不能改变,默认 Segment 的个数是 16 个,你也可以认...
