Original topic: jdbc执行过程做删除了sql中hit配置,岂不是所有的手工hit根本无法在线上使用
After using JDBC, the keyword [/*+ read_from_storage(tiflash[a,b]) */] is gone.
Could it be some configuration causing this? I haven’t encountered a similar issue before.
We need to find the reason why the hint is missing; it definitely shouldn’t happen under normal circumstances.
Check which package and version JDBC is using. What are the parameters?
There are no extra parameters.
You can try using a normal JDBC connection.
I guess it might be related to the behavior of the Druid framework. You can ask the Druid team about it.
