-----------------------------------------
Assignee: Konstantin Orlov
> Sql. Ability to create table without specifying PK
> --------------------------------------------------
>
> Key: IGNITE-16856
> URL: https://issues.apache.org/jira/browse/IGNITE-16856
> Project: Ignite
> Issue Type: New Feature
> Components: sql
> Reporter: Konstantin Orlov
> Assignee: Konstantin Orlov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha5
>
>
> Despite a keyless use case currently is not supported by Ignite-3, SQL
> standard allows to create such tables, and many external tests (TCP-H for
> instance) are taking advantage of this.
> To make it easier to adopt such a tests, let's provide a special mode for
> Ignite, where implicit PK will be created in case of lack explicit one.
> Key points to consider:
> * This mode considered for test purpose only, hence the implementation
> should be as less invasive as possible.
> * An implicit key column should not be returned by {{SELECT *}} queries. It
> may be accessed by its name though.
> * Type of this column doesn't matter, but the range of possible values
> should be big enough to support billiones of unique values.
