             Summary: Queries supporting regexp_extract function点击并应用
                 Key: KYLIN-5713
                 URL: https://issues.apache.org/jira/browse/KYLIN-5713
             Project: Kylin
          Issue Type: Improvement
    Affects Versions: 5.0-beta
            Reporter: Hongrong Cao
            Assignee: Ruixuan Zhang
             Fix For: 5.0.0


regexp_extract is supported in spark-sql, but not in kylin.
In kylin, you can set up regexp_extract related computable columns, verify that 
they work, and that they can be queried and decompressed normally after they 
are built.
Querying the regexp_extract function alone will also indicate that it is not 
supported, so it should be due to the fact that calcite does not support this 
function.
