Parallel Batching Architecture for Event Ordering and Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Event-based environments face complexity in managing large volumes of chronologically ordered data, leading to system overload and inefficiencies in processing and storage, particularly in environments like social media and sales platforms where data is rapidly generated and must be stored in a synchronized manner.
Innovation Solution
Implementing a parallel batching architecture with topic-based partitioning and a multi-layer retry mechanism, where events are assigned to 'swim lanes' for ordered processing, allowing for parallelism while maintaining data ordering, and utilizing a configurable queuing system to manage bandwidth and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a synchronous system is used to manage event data from multiple sources, then data consistency and chronological ordering are maintained, but the system becomes quickly overwhelmed and loses productivity during high load
Solution Approach 1:
The system segments event streams into multiple independent partitions based on topic and key, allowing parallel processing of different event groups while maintaining ordering within each partition. This segmentation enables the system to handle high throughput by distributing load across multiple workers while preserving data consistency through partition-specific ordering guarantees.
Solution Approach 2:
The patent introduces an intermediary batching layer between event ingestion and final storage/processing. Events are buffered in batches and processed as groups rather than individually, acting as a mediator that smooths out load peaks while maintaining chronological ordering within batches. This batching intermediary prevents system overload while preserving data consistency.
2Reliability
If events are processed in strict chronological order from all sources, then data ordering is maintained, but parallelism is reduced and processing time increases
Solution Approach 1:
The system divides the single global ordering requirement into multiple partition-specific ordering requirements. Each partition maintains chronological order independently, allowing parallel processing across partitions. This segmentation of ordering constraints enables concurrent processing while maintaining reliability of event sequences within each partition.
Solution Approach 2:
The patent transitions from a single-dimensional global ordering model to a multi-dimensional ordering model where ordering is maintained within partitions (one dimension) while parallelism operates across partitions (another dimension). This dimensional change allows simultaneous processing of multiple event streams while preserving chronological integrity within each stream.
3Reliability
If data is continuously pushed to remote storage without batching, then data freshness is maintained, but network overhead and storage system load increase significantly
Solution Approach 1:
The system implements periodic batching where events are accumulated and pushed to remote storage at regular intervals or when batch size thresholds are reached. This periodic action reduces network overhead and storage system load by consolidating multiple small writes into fewer larger operations, while maintaining data freshness through controlled batch intervals.
Solution Approach 2:
The patent merges multiple individual event push operations into consolidated batches before transmission to remote storage. By combining events into batches, the system reduces the total number of network transactions and storage operations, decreasing overall load and complexity while preserving data freshness through timely batch processing.
4Productivity
If the system processes all events from all users simultaneously, then comprehensive processing is achieved, but the system becomes complex and difficult to manage
Solution Approach 1:
The system segments the comprehensive processing task into independent partition processing units, each handling specific topic-key combinations. This segmentation maintains comprehensive processing coverage while simplifying management through modular, independently controllable processing units that can be monitored and managed separately.
Solution Approach 2:
The patent creates universal processing workers that can handle multiple partitions and event types through configurable parameters. These multi-functional workers reduce system complexity by using standardized processing logic across different partitions rather than requiring separate specialized handlers for each event stream.
Data Source
AI summary
In an event-based data management system, an event having an associated identifier is received. A mapping operation is performed using the identifier to map the event to a selected one of a plurality of topic partitions. Queues for each of the plurality of topic partitions are managed. The queues for each of the plurality of topic partitions are managed independently of each other. The event is allocated to the selected topic partition based on the mapping operation. The event is placed into the queue for the selected topic partition. A batch of events is sent from the queue for the selected topic partition in response to one or more thresholds being reached.
