Message Buffering and Intelligent Merged Reply Workflow
This workflow effectively handles continuously arriving chat messages through intelligent buffering and batch merging techniques. It utilizes the Redis caching mechanism to store messages and integrates with the OpenAI GPT-4 model for content consolidation, automatically generating merged responses to enhance conversation efficiency. By dynamically calculating wait times, it flexibly controls the timing of merges, avoids duplicate replies, and optimizes the message processing flow. This approach is particularly suitable for online customer service and intelligent Q&A systems, improving user experience and satisfaction.
Workflow Name
Message Buffering and Intelligent Merged Reply Workflow
Key Features and Highlights
This workflow implements intelligent buffering and batch merging of consecutive chat messages by leveraging Redis caching to store message data and utilizing the OpenAI GPT-4 model for content consolidation. It automatically generates a single merged reply. The workflow dynamically calculates wait times based on user message activity and message volume to flexibly control the merging timing, effectively preventing duplicate replies and unnecessary triggers, thereby enhancing conversation efficiency and user experience.
Core Problems Addressed
- How to effectively buffer and merge densely arriving chat messages to avoid resource waste and fragmented conversations caused by replying to each message individually?
- How to dynamically adjust wait times based on message length and activity levels to achieve intelligent delayed merging?
- How to use caching mechanisms to ensure correct synchronization of message states and concurrency control?
Application Scenarios
- Integration with online customer service bots to improve multi-turn dialogue context consolidation.
- Intelligent Q&A systems requiring content summarization of multiple user input messages before unified responses.
- Various chat applications aiming to reduce frequent replies and optimize message processing workflows.
- Complex dialogue management scenarios requiring automated message buffering and intelligent merging solutions.
Main Process Steps
- Message Reception and Buffering: Messages are received via chat trigger nodes and pushed into a Redis list
buffer_in:{context_id}, while updating message counts and last active timestamps. - Dynamic Wait Time Calculation: Wait time in seconds is determined based on message length (shorter messages have longer wait times) to control the merging timing.
- Concurrency Control: A flag
waiting_reply:{context_id}is set to prevent duplicate triggers for the same batch merging process. - Activity and Threshold Detection: The workflow checks the time difference between the last message and current time, as well as the number of buffered messages, to decide whether to initiate batch merging.
- Message Merging: All buffered messages are retrieved from Redis and passed to the OpenAI GPT-4 model with a custom system prompt to merge them into a single paragraph, deduplicating and consolidating all information.
- Output and Cache Cleanup: The merged message is output, and the corresponding Redis buffers and flags are cleared to prepare for the next message reception cycle.
Involved Systems or Services
- Redis: Used for message caching, counting, activity timestamping, and status flag management.
