ConnectorNodePartitioning

public ConnectorNodePartitioning(ConnectorPartitioningHandle partitioningHandle,
                                 List<ColumnHandle> partitioningColumns)

Method Detail

getPartitioningHandle

public ConnectorPartitioningHandle getPartitioningHandle()

A handle to the partitioning scheme used to divide the table across worker nodes.

getPartitioningColumns

public List<ColumnHandle> getPartitioningColumns()

The columns used to partition the table across the worker nodes. An empty list means the table is entirely contained on a single worker.

If the table is node partitioned, the connector guarantees that each combination of values for the distributed columns will be contained within a single worker.
