> 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.
