Micro-broker Communication Modes in Stream Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stream processing platforms face challenges in efficiently managing data communications between operators due to limitations in existing communication modes, which do not effectively adapt to relative locations, operator characteristics, and stream popularity, leading to suboptimal performance and resource utilization.
Innovation Solution
The implementation of micro-brokers that determine and support various communication modes such as shared queues, shared memory, point-to-point connections, or message brokers based on the relative locations and popularity of data streams, using instructions from a platform controller and network quality information to optimize data transmission between operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication mode is used for all operator communications, then system complexity is reduced, but communication efficiency and resource utilization deteriorate
Solution Approach 1:
The system dynamically selects communication modes (shared queue, shared memory, point-to-point connection, or message broker) based on real-time conditions including relative operator locations, stream popularity, and network quality. This dynamic adaptation resolves the contradiction by allowing the system to optimize communication efficiency for each specific scenario while maintaining manageable complexity through automated mode selection.
2Productivity
If micro-brokers dynamically determine communication modes based on multiple factors, then communication efficiency improves, but system complexity increases
Solution Approach 1:
The micro-broker incorporates feedback mechanisms that continuously monitor stream popularity, operator locations, and network quality to inform communication mode selections. This feedback-driven approach enables efficient adaptive decision-making without requiring overly complex manual configuration, as the system learns and adjusts based on observed performance metrics.
Solution Approach 2:
The micro-broker acts as an intermediary component that centralizes the complex decision-making logic for mode selection. By isolating this complexity in a dedicated intermediary component rather than distributing it throughout the entire system, the patent manages overall system complexity while still achieving dynamic optimization of communication efficiency.
3Reliability
If traditional message brokers are used for all communications, then communication reliability is maintained, but latency and resource utilization worsen
Solution Approach 1:
The system applies different communication modes tailored to specific local conditions: shared memory for co-located operators on the same host, shared queues for operators on different hosts, and message brokers for distributed systems. This local quality approach ensures reliability is maintained where needed while minimizing latency by using more direct communication paths when conditions permit.
