Event Stream Processing Acknowledgment via Segmented Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In event stream processing systems, there is a lack of efficient mechanisms for acknowledging and confirming the receipt of event block objects across geographically distributed sources and recipients, leading to potential data loss and processing inefficiencies.
Innovation Solution
A method is introduced that involves establishing separate connections for communicating with an event stream processing engine and a publishing/client device, where an event block object with a unique identifier is processed and acknowledged through these connections, ensuring successful processing is determined and acknowledged accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connections are established for ESP engine and publishing client, then reliability of acknowledgment is improved, but device complexity increases
Solution Approach 1:
The system segments communication into two distinct connections: a first connection between the ESP engine and publishing client for event block transmission, and a second connection between the ESP engine and subscribing client for acknowledgment transmission. This segmentation allows independent management of data transmission and acknowledgment pathways, improving reliability while maintaining manageable complexity through clear separation of concerns.
Solution Approach 2:
The ESP engine acts as an intermediary that receives event blocks from the publishing client via the first connection, processes them, and then sends acknowledgments back to the publishing client via the second connection. This intermediary role enables the system to maintain separate communication channels while ensuring reliable acknowledgment delivery without requiring direct peer-to-peer connections between all components.
2Reliability
If acknowledgment messages are sent through separate connection, then data integrity is improved, but communication overhead increases
Solution Approach 1:
By segmenting the communication protocol into distinct data transmission (first connection) and acknowledgment transmission (second connection) pathways, the system ensures that acknowledgment messages are not lost or corrupted with event block data. This segmentation improves data integrity by isolating critical acknowledgment traffic from potentially noisy data streams, while the overhead is managed through efficient connection reuse.
Solution Approach 2:
The system establishes the second connection for acknowledgments in advance, before data transmission begins. This preliminary setup ensures that the acknowledgment pathway is ready and validated, preventing communication failures during critical acknowledgment moments. The upfront connection establishment reduces the risk of data loss during transmission while the connection remains active for the duration of the data processing session.
3Measurement precision
If unique identifier is included in event block object, then tracking capability is improved, but information overhead increases
Solution Approach 1:
The system uses a compact unique identifier (such as a transaction ID or event block ID) that serves as a lightweight copy or reference to the original event block. This identifier is sufficient for tracking and acknowledgment purposes without requiring duplication of the entire event block data. The unique ID acts as a pointer that enables precise event tracking while minimizing information overhead by transmitting only the essential identification data rather than full event content.

AI summary
A method of acknowledging receipt of an event block object is provided. First connection information for connecting to an event stream processing (ESP) engine executing at a first computing device is received. A first connection to the ESP engine is established using the received first connection information. Second connection information for connecting to a publishing client executing at a second computing device is received. A second connection to the publishing client is established using the received second connection information, wherein the first connection differs from the second connection. An event block object is received from the ESP engine using the established first connection, wherein the event block object includes a unique identifier for the event block object. Successful processing of the event block object is determined. Responsive to the successful processing determination, an acknowledgment message including the unique identifier is sent to the publishing client using the established second connection.
