I want to create a Hashtable in Java program. The Hashtable must have multiple fields (for now i want to store 3 columns which i read from DB). How can I store multiple columns as Hashtable stor开发者
I\'m using hash_ring package for distributing objects among servers. I\'ve assumed that distribution would be uniform, as it\'s based on开发者_如何学JAVA MD5 hashes. Unfortunately it\'s not the case.
