|功能|所属模块|当前缺省错误条件判断|下一个版本优化|定制方法|下一个版本优化|功能说明|
|实例隔离|loadbalance|所有的错误，包括HTTP服务器500错误、不可达、超时等都纳入计数|1. InvocationException并且status code=490/590
 2. InvocationException以外的异常
 2.3.14+|无|待定|发往一个实例的请求如果失败超过一定次数，暂时给它隔离起来|
|调用重试|loadbalance|1. 重试本服务实例：ConnectException、SocketTimeoutException
 2. 重试另一个实例：所有的错误，包括参数检验错误|1. 重试本服务实例：ConnectException、SocketTimeoutException
 2. 重试另一个实例：同上
 2.3.14+|参考：https://github.com/apache/incubator-servicecomb-java-chassis/blob/master/demo/demo-jaxrs/jaxrs-client/src/main/java/org/apache/servicecomb/demo/jaxrs/client/CustomLoadbalanceExtensionsFactory.java|无|发往一个实例的请求失败，可以继续往这个实例，或者换一个实例发送请求|
|服务隔离|bizkeeper|1. InvocationException并且status code=490/590
 2. InvocationException以外的异常|待定|无|无|调用一个服务的接口失败超过一定次数，那么后续对这个接口的请求全部隔离起来|
