Apache Flink Overview. Apache Flink is an open-source platform that provides a scalable, distributed, fault-tolerant, and stateful stream processing capabilities. Flink is one of the most recent and pioneering Big Data processing frameworks. Apache Flink allows to ingest massive streaming data (up to several terabytes) from different sources. 1 Answer. A connect operation is more general then a join operation. Connect ensures that two streams (keyed or unkeyed) meet at the same location (at the same parallel instance within a CoXXXFunction). One stream could be a control stream that manipulates the behavior applied to the other stream. For example, you could stream-in new machine.
