Method Detail

listPartitionHandles

default List<ConnectorPartitionHandle> listPartitionHandles(ConnectorTransactionHandle transactionHandle,
                                                            ConnectorSession session,
                                                            ConnectorPartitioningHandle partitioningHandle)

Returns a list of all partitions associated with the provided partitioningHandle.

This method must be implemented for connectors that support addressable split discovery. The partitions return here will be used as address for the purpose of split discovery.

getBucketToNode

Map<Integer,Node> getBucketToNode(ConnectorTransactionHandle transactionHandle,
                                  ConnectorSession session,
                                  ConnectorPartitioningHandle partitioningHandle)

getSplitBucketFunction

ToIntFunction<ConnectorSplit> getSplitBucketFunction(ConnectorTransactionHandle transactionHandle,
                                                     ConnectorSession session,
                                                     ConnectorPartitioningHandle partitioningHandle)

getBucketFunction

BucketFunction getBucketFunction(ConnectorTransactionHandle transactionHandle,
                                 ConnectorSession session,
                                 ConnectorPartitioningHandle partitioningHandle,
                                 List<Type> partitionChannelTypes,
                                 int bucketCount)
