Examples of com.facebook.presto.spi.ConnectorPartitionResult

com.facebook.presto.spi.ConnectorPartitionResult
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.
