You can now use the Azure Data Factory copy activity to ingest data from Netezza with out-of-box parallel copy to boost performance. With Netezza data slice partition and dynamic range partition support, Data Factory can run parallel queries against your Netezza source to load data by partitions concurrently, increasing performance. For more information, see Netezza connector – Parallel copy from Netezza.
