 * Write builder trait for tables that support dynamic partition overwrite.

 * partition for which the write will commit new data. Any existing logical partition for which the
 * write does not contain data will remain unchanged.
 * <p>
 * This is provided to implement SQL compatible with Hive table operations but is not recommended.
 * Instead, use the {@link SupportsOverwrite overwrite by filter API} to explicitly replace data.
