[GitHub] [shardingsphere] strongduanmu opened a new issue #10908: RelSubset has wrong best cost error occur when execute federate query with shardingsphere-integration-test-suite
strongduanmu opened a new issue #10908:
URL: https://github.com/apache/shardingsphere/issues/10908
## Bug Report
### Which version of ShardingSphere did you use?
master branch
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
return result without exception
### Actual behavior
```
java.lang.AssertionError: RelSubset [rel#58:RelSubset#3.ENUMERABLE.[]] has wrong best cost {2490.0 rows, 402.0 cpu, 0.0 io}. Correct cost is {15175.5 rows, 251.505 cpu, 0.0 io}

[GitHub] [shardingsphere] strongduanmu commented on issue #10908: RelSubset has wrong best cost error occur when execute federate query with shardingsphere-integration-test-suite

As can be seen from the `VolcanoPlanner` source code, this exception will only be checked when `isDebugEnabled=true`. This problem can be avoided by adjusting the log level.
```java
public RelSubset ensureRegistered(RelNode rel, RelNode equivRel) {
RelSubset result;
final RelSubset subset = getSubset(rel);
if (subset != null) {
if (equivRel != null) {
final RelSubset equivSubset = getSubset(equivRel);
if (subset.set != equivSubset.set) {
merge(equivSubset.set, subset.set);
}
}
result = canonize(subset);
} else {
result = register(rel, equivRel);
}
// Checking if tree is valid considerably slows down planning
