> Key: IGNITE-4141
> URL: https://issues.apache.org/jira/browse/IGNITE-4141
> Project: Ignite
> Issue Type: Improvement
> Components: jdbc
> Affects Versions: 1.7
> Reporter: Valentin Kulichenko
> Assignee: Evgenii Zhuravlev
> Fix For: 2.0

> Generally there are no model classes on the client which uses JDBC driver. This means that an attempt to query {{_key}} and {{_val}} fields (which are included in {{select *}}) will fail with "Failed resolve class for ID" error. To avoid this we should always set {{withKeepBinary()}} flag when executing query on server side.
