> The {{JdbcDatabaseAccessor}} associated with the storage handler makes some
> SQL calls to the RDBMS through the JDBC connection. There is a
> {{GenericJdbcDatabaseAccessor}} with a generic implementation that the
> storage handler uses if there is no specific implementation for a certain
> RDBMS.
> Currently, Hive uses the {{GenericJdbcDatabaseAccessor}}. Afaik the only
> generic query that will not work is splitting the query based on offset and
> limit, since the syntax for that query is different than the one accepted by
> Hive. We should create a {{HiveJdbcDatabaseAccessor}} to override that query
> and possibly fix any other existing incompatibilities.
