Streaming data processing method and device based on computing program chain and storage medium

The invention provides a streaming data processing method and device based on a calculation program chain and a storage medium, and the method comprises the steps: receiving a calculation logic expression which represents a total calculation task needing to be completed by a whole flow calculation pipeline; the calculation logic expression is analyzed to obtain a target calculation program chain, the target calculation program chain comprises at least one calculation unit instance, and the at least one calculation unit instance achieves data transmission according to the logic sequence determined by the calculation logic expression; running the target calculation program chain to receive original data pushed by the data source, and triggering at least one calculation unit instance to sequentially execute corresponding calculation tasks according to the logic sequence; and outputting target result data obtained by the target calculation program chain aiming at the original data. According to the invention, the
