> _key and _val fields should be excluded from 'select * from' queries

> Key: IGNITE-3487
> URL: https://issues.apache.org/jira/browse/IGNITE-3487
> Project: Ignite
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6
> Reporter: Valentin Kulichenko
> Assignee: Sergey Kalashnikov
> Labels: important
> Fix For: 2.0
>
>
> We have a pretty serious usability issue - predefined {{_key}} and {{_val}}
> fields are returned when query like {{select * from}} is executed. First of
> all, this is counterintuitive because user never defines or configures these
> fields. Second of all, they actually duplicate all other fields. And finally,
> they cause serialization exceptions because classes for key and value are not
> always available.
> We should exclude these fields from {{select * from}} queries, but this is a
> compatibility breaking change. It should be done in 2.0.
