lightyear007 opened a new issue #4028: If not hint values are set what's the routing behavior for HintShardingAlgorithm URL: https://github.com/apache/incubator-shardingsphere/issues/4028 According to sharding jdbc doc [https://shardingsphere.apache.org/document/current/cn/manual/sharding-jdbc/usage/hint/], if we want to use the forced routing, we have to implement a HintShardingAlgorithm. My question is that if we have configured a sharding rule using HintShardingAlgorithm, but we didn't set any hint values using the HintManager, then how sharding jdbc can get a clue of how to route the query? I tried this and found out, if no values are set, my HintShardingAlgorithm implementation code will not be executed. then i would what rule sharding jdbc is using in this case. Thanks Jacky
