 * Result of fetching Partitions in the ConnectorSplitManager interface.

 * Results are comprised of two parts:
 * 1) The actual partitions
 * 2) The TupleDomain that represents the values that the connector was not able to pre-evaluate
 * when generating the partitions and will need to be double-checked by the final execution plan.
