Solution Overview
Problem
Database systems are not well-suited for real-time processing and analysis of large amounts of streaming data, as they struggle to efficiently store, index, and analyze data in real-time.
Innovation Solution
A stream-based computing method that utilizes dynamic connections between stream operators to process streaming data, allowing for the modification of processing based on the presence or absence of these connections, enabling efficient real-time processing and analysis by dynamically managing the flow of tuples through the operator graph.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If database systems are used to store and process streaming data, then data storage and indexing capabilities are provided, but real-time processing efficiency and scalability deteriorate
Solution Approach 1:
The system segments the stream processing architecture into multiple independent stream operators that can be dynamically connected and disconnected. Each operator processes specific portions of the data stream independently, allowing parallel processing while maintaining storage reliability through the structured operator graph framework.
Solution Approach 2:
The patent implements dynamic connections between stream operators that can be established or removed at runtime based on processing needs. This dynamic architecture allows the system to scale processing capacity up or down without reconfiguring the entire system, resolving the contradiction between reliable storage structure and flexible real-time processing.
2Loss of information
If traditional database systems process streaming data, then data analysis is performed, but processing speed and real-time performance worsen
Solution Approach 1:
The system performs preliminary actions by pre-configuring the operator graph structure and data flow paths before streaming data arrives. Stream operators are pre-positioned and connected in advance, allowing immediate processing of incoming data without the overhead of dynamic configuration during data flow, thus maintaining both analysis capability and high processing speed.
Solution Approach 2:
The stream processing system maintains continuous operation of stream operators once initialized, eliminating the start-stop cycles typical of batch database processing. The operator graph enables continuous data flow through multiple processing stages simultaneously, ensuring that data analysis occurs continuously at high speed without interruption or reconfiguration overhead.
3Adaptability or versatility
If stream operators are dynamically connected to handle varying processing needs, then processing flexibility improves, but system complexity increases
Solution Approach 1:
The stream operator framework implements universal connection interfaces and standardized data flow protocols that allow different operators to be connected in various configurations without requiring custom integration logic for each connection scenario. This multi-functionality enables flexible processing topologies while maintaining manageable system complexity through interface standardization.
Solution Approach 2:
The operator graph serves as an intermediary layer that manages connections between stream operators. Rather than operators directly managing complex peer-to-peer connections, the graph structure provides a simplified abstraction that handles routing and connectivity, reducing the complexity burden on individual operators while enabling flexible system-wide configurations.
Data Source
AI summary
One embodiment is directed to a method for processing a stream of tuples in a stream-based application. A stream operator may receive a stream of tuples. A stream manager may determine whether a dynamic connection exists at a first stream operator. The dynamic connection may connect the first stream operator to a second stream operator. The stream manager may poll the first stream operator and the second stream operator for a presence of the dynamic connection. The stream manager may modify processing of one or more upstream stream operators in response to a change in use of the dynamic connection.
