One writer can write data to multiple buckets (also called partitions) at the same time but only one file per bucket can be in progress (aka open) state. See the Multi-Engine Support#apache-flink page for the integration of Apache Flink.
You first need to have a source connector which can be used in Flinks runtime system, defining how data goes in and how it can be executed in the cluster.
