+
 > `--input-dir` 参数指定要扫描的输入目录。您可以从 webui 触发输入目录扫描。

+### 启动多个LightRAG实例
+
+有两种方式可以启动多个LightRAG实例。第一种方式是为每个实例配置一个完全独立的工作环境。此时需要为每个实例创建一个独立的工作目录，然后在这个工作目录上放置一个当前实例专用的`.env`配置文件。不同实例的配置文件中的服务器监听端口不能重复，然后在工作目录上执行 lightrag-server 启动服务即可。
+
+第二种方式是所有实例共享一套相同的`.env`配置文件，然后通过命令行参数来为每个实例指定不同的服务器监听端口和工作空间。你可以在同一个工作目录中通过不同的命令行参数启动多个LightRAG实例。例如：
+
+```
+# 启动实例1
+lightrag-server --port 9621 --workspace space1
+
+# 启动实例2
+lightrag-server --port 9622 --workspace space2
+```
+
+工作空间的作用是实现不同实例之间的数据隔离。因此不同实例之间的`workspace`参数必须不同，否则会导致数据混乱，数据将会被破坏。
+
+### LightRAG实例间的数据隔离
+
+每个实例配置一个独立的工作目录和专用`.env`配置文件通常能够保证内存数据库中的本地持久化文件保存在各自的工作目录，实现数据的相互隔离。LightRAG默认存储全部都是内存数据库，通过这种方式进行数据隔离是没有问题的。但是如果使用的是外部数据库，如果不同实例访问的是同一个数据库实例，就需要通过配置工作空间来实现数据隔离，否则不同实例的数据将会出现冲突并被破坏。
+
+命令行的 workspace 参数和`.env`文件中的环境变量`WORKSPACE` 都可以用于指定当前实例的工作空间名字，命令行参数的优先级别更高。下面是不同类型的存储实现工作空间的方式：
+
+- **对于本地基于文件的数据库，数据隔离通过工作空间子目录实现：** JsonKVStorage, JsonDocStatusStorage, NetworkXStorage, NanoVectorDBStorage, FaissVectorDBStorage。
+- **对于将数据存储在集合（collection）中的数据库，通过在集合名称前添加工作空间前缀来实现：** RedisKVStorage, RedisDocStatusStorage, MilvusVectorDBStorage, QdrantVectorDBStorage, MongoKVStorage, MongoDocStatusStorage, MongoVectorDBStorage, MongoGraphStorage, PGGraphStorage。
+- **对于关系型数据库，数据隔离通过向表中添加 `workspace` 字段进行数据的逻辑隔离：** PGKVStorage, PGVectorStorage, PGDocStatusStorage。
+
+* **对于Neo4j图数据库，通过label来实现数据的逻辑隔离**：Neo4JStorage
+
+为了保持对遗留数据的兼容，在未配置工作空间时PostgreSQL的默认工作空间为`default`，Neo4j的默认工作空间为`base`。对于所有的外部存储，系统都提供了专用的工作空间环境变量，用于覆盖公共的 `WORKSPACE`环境变量配置。这些适用于指定存储类型的工作空间环境变量为：`REDIS_WORKSPACE`, `MILVUS_WORKSPACE`, `QDRANT_WORKSPACE`, `MONGODB_WORKSPACE`, `POSTGRES_WORKSPACE`, `NEO4J_WORKSPACE`。

 ### Gunicorn + Uvicorn 的多工作进程

 LightRAG 服务器可以在 `Gunicorn + Uvicorn` 预加载模式下运行。Gunicorn 的多工作进程（多进程）功能可以防止文档索引任务阻塞 RAG 查询。使用 CPU 密集型文档提取工具（如 docling）在纯 Uvicorn 模式下可能会导致整个系统被阻塞。

-The `.env` file **must be placed in the startup directory**.

-Upon launching, the LightRAG Server will create a documents directory (default is `./inputs`) and a data directory (default is `./rag_storage`). This allows you to initiate multiple instances of LightRAG Server from different directories, with each instance configured to listen on a distinct network port.
+When starting LightRAG, the current working directory must contain the `.env` configuration file. **It is intentionally designed that the `.env` file must be placed in the startup directory**. The purpose of this is to allow users to launch multiple LightRAG instances simultaneously and configure different `.env` files for different instances. **After modifying the `.env` file, you need to reopen the terminal for the new settings to take effect.** This is because each time LightRAG Server starts, it loads the environment variables from the `.env` file into the system environment variables, and system environment variables have higher precedence.

 - `--timeout`: LLM request timeout (default: 150 seconds)
- `--log-level`: Logging level (default: INFO)
- `--input-dir`: Specifying the directory to scan for documents (default: ./inputs)

-> - The requirement for the .env file to be in the startup directory is intentionally designed this way. The purpose is to support users in launching multiple LightRAG instances simultaneously, allowing different .env files for different instances.
-> - **After changing the .env file, you need to open a new terminal to make  the new settings take effect.** This because the LightRAG Server will load the environment variables from .env into the system environment variables each time it starts, and LightRAG Server will prioritize the settings in the system environment variables.
+- `--log-level`: Log level (default: INFO)
+- `--working-dir`: Database persistence directory (default: ./rag_storage)
+- `--input-dir`: Directory for uploaded files (default: ./inputs)
+- `--workspace`: Workspace name, used to logically isolate data between multiple LightRAG instances (default: empty)

+When starting the LightRAG Server with the `--auto-scan-at-startup` parameter, the system will automatically:

 1. Scan for new files in the input directory
 2. Index new documents that aren't already in the database
 3. Make all content immediately available for RAG queries

+This offers an efficient method for deploying ad-hoc RAG processes.
+
 > The `--input-dir` parameter specifies the input directory to scan. You can trigger the input directory scan from the Web UI.

+### Starting Multiple LightRAG Instances
+
+There are two ways to start multiple LightRAG instances. The first way is to configure a completely independent working environment for each instance. This requires creating a separate working directory for each instance and placing a dedicated `.env` configuration file in that directory. The server listening ports in the configuration files of different instances cannot be the same. Then, you can start the service by running `lightrag-server` in the working directory.
+
+The second way is for all instances to share the same set of `.env` configuration files, and then use command-line arguments to specify different server listening ports and workspaces for each instance. You can start multiple LightRAG instances in the same working directory with different command-line arguments. For example:
+
+```
+# Start instance 1
+lightrag-server --port 9621 --workspace space1
+
+# Start instance 2
+lightrag-server --port 9622 --workspace space2
+```
+
+The purpose of a workspace is to achieve data isolation between different instances. Therefore, the `workspace` parameter must be different for different instances; otherwise, it will lead to data confusion and corruption.
+
+### Data Isolation Between LightRAG Instances
+
+Configuring an independent working directory and a dedicated `.env` configuration file for each instance can generally ensure that locally persisted files in the in-memory database are saved in their respective working directories, achieving data isolation. By default, LightRAG uses all in-memory databases, and this method of data isolation is sufficient. However, if you are using an external database, and different instances access the same database instance, you need to use workspaces to achieve data isolation; otherwise, the data of different instances will conflict and be destroyed.
+
+The command-line `workspace` argument and the `WORKSPACE` environment variable in the `.env` file can both be used to specify the workspace name for the current instance, with the command-line argument having higher priority. Here is how workspaces are implemented for different types of storage:
+
+- **For local file-based databases, data isolation is achieved through workspace subdirectories:** `JsonKVStorage`, `JsonDocStatusStorage`, `NetworkXStorage`, `NanoVectorDBStorage`, `FaissVectorDBStorage`.
+- **For databases that store data in collections, it's done by adding a workspace prefix to the collection name:** `RedisKVStorage`, `RedisDocStatusStorage`, `MilvusVectorDBStorage`, `QdrantVectorDBStorage`, `MongoKVStorage`, `MongoDocStatusStorage`, `MongoVectorDBStorage`, `MongoGraphStorage`, `PGGraphStorage`.
+- **For relational databases, data isolation is achieved by adding a `workspace` field to the tables for logical data separation:** `PGKVStorage`, `PGVectorStorage`, `PGDocStatusStorage`.
+- **For the Neo4j graph database, logical data isolation is achieved through labels:** `Neo4JStorage`
+
+To maintain compatibility with legacy data, the default workspace for PostgreSQL is `default` and for Neo4j is `base` when no workspace is configured. For all external storages, the system provides dedicated workspace environment variables to override the common `WORKSPACE` environment variable configuration. These storage-specific workspace environment variables are: `REDIS_WORKSPACE`, `MILVUS_WORKSPACE`, `QDRANT_WORKSPACE`, `MONGODB_WORKSPACE`, `POSTGRES_WORKSPACE`, `NEO4J_WORKSPACE`.
+
 ### Multiple workers for Gunicorn + Uvicorn

 The LightRAG Server can operate in the `Gunicorn + Uvicorn` preload mode. Gunicorn's multiple worker (multiprocess) capability prevents document indexing tasks from blocking RAG queries. Using CPU-exhaustive document extraction tools, such as docling, can lead to the entire system being blocked in pure Uvicorn mode.
