-----------------------------------
> 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
> Priority: Major
> Labels: sql-engine
>
> 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.
