Subject [jira] [Created] (IGNITE-6292) SQL: Support CHECK constraint
Date Thu, 07 Sep 2017 13:00:08 GMT
Vladimir Ozerov created IGNITE-6292:

             Summary: SQL: Support CHECK constraint
                 Key: IGNITE-6292
                 URL: https://issues.apache.org/jira/browse/IGNITE-6292
             Project: Ignite
          Issue Type: Task
          Components: sql
    Affects Versions: 2.1
            Reporter: Vladimir Ozerov

Currently we do not support {{CHECK}} constraint, which is very important in SQL world. Need
to investigate how we can add it. Essentially, we have two ways:
1) Either delegate constraint validation to H2 somehow. But remember that we should do that
early during update, and we should do that efficiently. Need to investigate H2 API to find
out how to achieve that.
2) Or we should wait for development of our own execution engine, which is a huge thing and
would not appear fast. In this case we would be able to pre-compile expression somehow and
execute it whenever we want.
