[jira] [Created] (IGNITE-4141) JDBC driver should always set withKeepBinary flag when querying cache

Valentin Kulichenko created IGNITE-4141:
-------------------------------------------

             Summary: JDBC driver should always set withKeepBinary flag when querying cache
                 Key: IGNITE-4141
                 URL: https://issues.apache.org/jira/browse/IGNITE-4141
             Project: Ignite
          Issue Type: Improvement
          Components: jdbc-driver
    Affects Versions: 1.7
            Reporter: Valentin Kulichenko


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.
