Llamaindex workflows. 了解如何在LlamaIndex中创建和管理工作流，包括定义事件、使用装饰器、可视化流程以及处理多个事件以实现更高级的功能。 Concurrent execution of workflows In addition to looping and branching, workflows can run steps concurrently. This is useful when you have multiple steps that can be run independently of each other and they have time-consuming operations that they await, allowing other steps to run in parallel. Validation happens once, when the workflow starts, and does not produce much overhead. Workflows offer several key benefits: Clear organization of code into discrete Workflows A Workflow in LlamaIndex is a lightweight, event-driven abstraction used to chain together several events. - run-llama/workflows-py Workflows provide basic validation to catch potential runtime errors as soon as possible. 0, a lightweight framework for building complex, multi-step agentic AI applications in Python and Typescript. It provides a simple and lightweight orchestration solution for building complex workflows with minimal boilerplate. May 5, 2024 · By leveraging these advanced workflows and the capabilities of LlamaIndex, you can create sophisticated LLM applications that cater to complex tasks and user interactions. Jun 30, 2025 · We’re excited to introduce the official release of LlamaIndex Workflows 1. LlamaIndex Workflows are a library for event-driven programming in JavaScript and TypeScript. Use an instance of a Workflow class to run a workflow and stream events produced during execution. But . Workflows are made up of steps that handle events and emit new events, and can be visualized and instrumented. Your application is divided into sections called Steps which are triggered by Events, and themselves emit Events which trigger further steps. Workflows are made up of handlers, with each one responsible for processing specific event types and emitting new events. - run-llama/llama_index A Workflow in LlamaIndex is a lightweight, event-driven abstraction used to chain together several events. Emitting multiple events In our examples so far, we've only emitted one event from each step. Such a workflow is created by defining Steps which are triggered by Events, and themselves emit Events to trigger further steps. Learn how to create and run workflows with LlamaIndex, a library for building applications with large language models. Let’s take a look at Alfred showing a LlamaIndex workflow for a RAG task. It combines event-driven programming, async context and streaming to create a flexible and efficient way to handle data processing tasks. Sep 20, 2024 · Context类似LangGraph中的State（状态），但LlamaIndex中各Step的数据交换更多通过event传递，而不是Context。 最后总结：LlamaIndex Workflows是通过一种事件驱动、自我管理的任务组件（step）来组装与编排复杂工作流的方式。 Workflows introduction What is a workflow? A workflow is an event-driven, step-based way to control the execution flow of an application. It can be disabled in any case. Workflows are an event-driven, async-first, step-based way to control the execution flow of AI applications like agents. A workflow in LlamaIndex provides a structured way to organize your code into sequential and manageable steps. LlamaIndex is the leading framework for building LLM-powered agents over your data. rxx ssfplg abgn zuv lebnz jpwu vyl tmscjg ufhi citjr
