> Per ARROW-16427, JDBC drivers sometimes return ResultSets where the scale of
> BigDecimals in a single column differs by row. The existing mapping requires
> exact match of scale to the target Arrow vector that was created based on
> ResultSetMetaData (or configuration), and when any row does not match
> exactly, an Exception is thrown.
> To support JDBC drivers where scale may be inconsistent by row, Arrow should
> allow a less-strict mode that coerces BigDecimals to target vectors with
> greater scale. The default strict behavior should be retained, but it may be
> useful to allow coercion to proper target scale.
