org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.fromCollection()
Creates a DataStream from the given non-empty collection. The type of the DataStream is that of the elements in the collection. The elements need to be serializable (as defined by java.io.Serializable), because the framework may move the elements into the cluster if needed. @param data The collection of elements to create the DataStream from. @param < OUT> type of the returned stream @return The DataStream representing the elements.
