> Fix SQL select by _key for a composite pk in Calcite engine
> -----------------------------------------------------------
>
> Key: IGNITE-28331
> URL: https://issues.apache.org/jira/browse/IGNITE-28331
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.17
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: ignite-2
> Time Spent: 8h
> Remaining Estimate: 0h
>
> I discovered that for a simple pk (consisting of one column), queries like
> "select name from person where _key = ?" use the pk index with a single-value
> lookup.
> However, if the pk is composite, a full scan of the primary key index will be
> used. This is neither obvious nor efficient; this needs to be fixed for the
> Calcite engine.
