Riza Suminto commented on IMPALA-10960:
---------------------------------------
Hi All, I think this is generally useful.
Since the proposed comment evaluation is though regex, I just want to brought
attention to IMPALA-9615 and IMPALA-9614 so that this does not hit the same
problem.

> SQL comment can be used to describe the SQL statements. with comments
> containing information about the SQL statements, This may help in easily
> correlating slow performance with source code.
> For better to use sql comment, we can set the sql comment rule with regular
> expression
> eg: set
> sql_comment_rule=/\*\s*author:\S+\s*?project:\S+\s*?desc:\S+\s*?.+\*/.+?;
> this example means that if the SQL statement want be addmitted by impala,
> its sql comment must include auther. project and desc's infomation. then we
> can trace the sql‘s origin.
> there are two steps:
> # Set sql_comment_rule by own way, with set sql_comment_rule query option in
> regular expression
> # Check the query‘s legality based on the sql_comment_rule which we have
> set. if check succeed, SQL can be admitted to Coordinator. otherwise, will
> refuse the query.
