分布式计数器,默认是redis实现,可扩展接口增加zk、等其他实现
The -- operator decrements its single operand by one. When used in prefix mode, it decrements the operand and evaluates to the decremented value of that operand. When used in postfix mode, it decrements its operand, but evaluates to the value of that operand before it was decremented.
Add a description, image, and links to the decrement topic page so that developers can more easily learn about it.
