Data sources provide connections , pooled connections , and distributed connections without hard - coding connection properties into java code 数据源可提供连接、池化连接和分布式连接,并且无需将连接属性硬编码到java代码中。
Round robin would distribute connection attempts evenly among the channels , while hashing would use the client s ip address to determine the destination channel 轮流调度方式会将连接尝试均匀地分布到各个通道上,而散列方法则使用客户机的ip地址来确定目标通道。
