----------------------------------
Summary: Query SQL association order change causes the model to
fail to hit
Key: KYLIN-5521
URL: https://issues.apache.org/jira/browse/KYLIN-5521
Project: Kylin
Issue Type: Bug
Components: Query Engine
Reporter: Yaguang Jia
In the log, the following two query statements, only the order of the
association of the first 2 tables is changed (the actual logical relationship
has not changed), resulting in the query statement can not be hit by the same
index. When there are only 2 tables after from, the order of the replacement
table association can hit the same index.
日志中，以下两条查询语句，只是前面2张表的关联先后顺序换了一下（实际逻辑关系并未改变），导致查询语句不能被同一个索引击中。而当from后面只有2张表时，替换表关联的先后顺序是可以击中同一个索引的。
