Methods

Modifier and Type	Method and Description
ConnectorPartitionResult	getPartitions(ConnectorTableHandle table, TupleDomain<ConnectorColumnHandle> tupleDomain) Gets the Partitions for the specified table.
ConnectorSplitSource	getPartitionSplits(ConnectorTableHandle table, List<ConnectorPartition> partitions) Gets the Splits for the specified Partitions in the indicated table.

Method Detail

getPartitions

ConnectorPartitionResult getPartitions(ConnectorTableHandle table,
                                     TupleDomain<ConnectorColumnHandle> tupleDomain)

Gets the Partitions for the specified table. The TupleDomain indicates the execution filters that will be directly applied to the data stream produced by this connector. Connectors are encouraged to take advantage of this information to perform connector-specific optimizations.

getPartitionSplits

ConnectorSplitSource getPartitionSplits(ConnectorTableHandle table,
                                      List<ConnectorPartition> partitions)

Gets the Splits for the specified Partitions in the indicated table.
