Redis 存储

Redis 存储实现通过 node-redis（Node.js 官方 Redis client）的直接 Redis 连接提供高性能存储解决方案。它支持独立 Redis，也可通过自定义 client 配置支持 Redis Sentinel 和 Cluster 部署。

安装

npm install @mastra/redis

使用方法

使用连接字符串

import { RedisStore } from '@mastra/redis'

const storage = new RedisStore({
  id: 'redis-storage',
  connectionString: 'redis://localhost:6379',
})

await storage.init()

使用 Host/Port 配置

import { RedisStore } from '@mastra/redis'

const storage = new RedisStore({
  id: 'redis-storage',
  host: 'localhost',
  port: 6379,
  password: 'your-password',
  db: 0,
})

await storage.init()

使用预配置的 Client

对于 Sentinel 或 Cluster 等高级配置，你可以传入预配置的 Redis client：

import { RedisStore } from '@mastra/redis'
import { createClient } from 'redis'

const client = createClient({
  url: 'redis://localhost:6379',
  socket: {
    reconnectStrategy: retries => Math.min(retries * 50, 2000),
  },
})

// Connect the client before passing to RedisStore
await client.connect()

const storage = new RedisStore({
  id: 'redis-storage',
  client,
})

参数

id:

string

storage 实例的唯一标识符

connectionString?:

string

Redis 连接 URL（例如 redis://localhost:6379 或 redis://:password@localhost:6379）

host?:

string

Redis host 地址

port?:

number

= 6379

Redis port 号

password?:

string

用于身份验证的 Redis password

db?:

number

= 0

Redis database 号

client?:

RedisClient

用于高级设置的预配置 redis client（来自 redis package）

备注

你必须提供 connectionString、host 或 client 之一。这些选项互斥。

其他说明

Key 结构

Redis 存储实现使用以下 key 模式：

• Thread：mastra_threads:id:{threadId}
• Message：mastra_messages:threadId:{threadId}:id:{messageId}
• Message 索引：msg-idx:{messageId}（用于快速查找）
• Thread message 有序集合：thread:{threadId}:messages
• Workflow 快照：mastra_workflow_snapshot:namespace:{ns}:workflow_name:{name}:run_id:{id}
• Score：mastra_scorers:id:{scoreId}
• Resource：mastra_resources:{resourceId}

Redis Sentinel

对于使用 Redis Sentinel 的高可用部署，请创建自定义 client：

import { RedisStore } from '@mastra/redis'
import { createClient } from 'redis'

const client = createClient({
  url: 'redis://sentinel-host:26379',
  // Configure sentinel options as needed for your setup
})

await client.connect()

const storage = new RedisStore({
  id: 'redis-sentinel-storage',
  client,
})

Redis Cluster

对于 Redis Cluster 部署，请使用 cluster client：

import { RedisStore } from '@mastra/redis'
import { createCluster } from 'redis'

const cluster = createCluster({
  rootNodes: [
    { url: 'redis://node-1:6379' },
    { url: 'redis://node-2:6379' },
    { url: 'redis://node-3:6379' },
  ],
})

await cluster.connect()

const storage = new RedisStore({
  id: 'redis-cluster-storage',
  client: cluster,
})

访问底层 Client

你可以访问底层 Redis client 以执行自定义操作：

const storage = new RedisStore({
  id: 'redis-storage',
  connectionString: 'redis://localhost:6379',
})

await storage.init()

const client = storage.getClient()

// Custom Redis operations
await client.set('custom-key', 'value')
const value = await client.get('custom-key')

关闭连接

关闭应用程序时，请关闭 Redis 连接：

await storage.close()

使用示例

向 agent 添加 memory

src/mastra/agents/redis-agent.ts

import { Memory } from '@mastra/memory'
import { Agent } from '@mastra/core/agent'
import { RedisStore } from '@mastra/redis'

export const redisAgent = new Agent({
  id: 'redis-agent',
  name: 'Redis Agent',
  instructions:
    'You are an AI agent with the ability to automatically recall memories from previous interactions.',
  model: 'openai/gpt-5.6-sol',
  memory: new Memory({
    storage: new RedisStore({
      id: 'redis-agent-storage',
      connectionString: process.env.REDIS_URL!,
    }),
    options: {
      lastMessages: 10,
    },
  }),
})

使用 agent

src/test-redis-agent.ts

import 'dotenv/config'

import { mastra } from './mastra'

const threadId = '123'
const resourceId = 'user-456'

const agent = mastra.getAgent('redisAgent')

const message = await agent.stream('My name is Mastra', {
  memory: {
    thread: threadId,
    resource: resourceId,
  },
})

await message.textStream.pipeTo(new WritableStream())

const stream = await agent.stream("What's my name?", {
  memory: {
    thread: threadId,
    resource: resourceId,
  },
  memoryOptions: {
    lastMessages: 5,
  },
})

for await (const chunk of stream.textStream) {
  process.stdout.write(chunk)
}

与 Mastra 实例一起使用

import { Mastra } from '@mastra/core'
import { RedisStore } from '@mastra/redis'

const storage = new RedisStore({
  id: 'mastra-storage',
  host: 'localhost',
  port: 6379,
})

const mastra = new Mastra({
  storage, // init() called automatically
})

如果不通过 Mastra 直接使用 storage，请显式调用 init()：

import { RedisStore } from '@mastra/redis'

const storage = new RedisStore({
  id: 'redis-storage',
  host: 'localhost',
  port: 6379,
})

await storage.init()

// Access domain-specific stores via getStore()
const memoryStore = await storage.getStore('memory')
const thread = await memoryStore?.getThreadById({ threadId: '...' })
