OpenClaw + Hologres: AI Agent Long-Term Memory Setup Guide

Learn how to set up OpenClaw with Hologres and Mem0 for enterprise-grade AI Agent long-term memory. Cross-device sync, vector search, step-by-step guide.

What This Is All About

OpenClaw is a pretty neat open-source personal AI assistant. You can chat with it through all kinds of messaging apps, and it plays nice with Alibaba Cloud's Qwen models.

Then there's Mem0 — think of it as a memory layer for AI. It handles the heavy lifting: pulling out important stuff from conversations, turning it into vectors, storing it, and bringing it back when you need it. It's what gives your LLM that "I remember you" capability across different sessions.

Now, Hologres enters the picture. It's Alibaba Cloud's real-time data warehouse that's got some serious vector search chops. The cool part? They've open-sourced a Hologres and Mem0 integration. When you put Hologres behind Mem0, your OpenClaw instance gets cloud-based memory that syncs across devices and won't disappear if your laptop crashes.

Good reads if you want to dig deeper:

How It Works

Here's the flow — pretty straightforward once you break it down:

1. Extract — Mem0 scans what you type and figures out what's worth remembering. Not everything needs to go into long-term storage.

2. Embed — Takes those important bits and runs them through an embedding model (text-embedding-v4 works great). Now you've got vectors.

3. Store — Hologres gets the vectors, the original text, and some metadata. Everything's written in real-time, so nothing gets lost.

4. Retrieve — When you ask something new, it gets turned into a vector too. Then Hologres runs a vector similaritysearch using its HGraph index to find relevant memories.

5. Fuse — Those memories get woven into the context so your AI assistant actually knows what you're talking about.

Why Bother?

For OpenClaw Users

If you're using OpenClaw, this setup gives you:

  • Your memories, everywhere — Work laptop, home computer, phone — doesn't matter. Your AI assistantremembers your preferences and past chats across all of them.
  • No more "wait, what did I tell you?" — Your data lives in Hologres on the cloud. Swap machines, reinstall your OS, it's all still there.
  • Actually helpful responses — When your assistant remembers your habits and preferences, it just works better.
  • Enterprise-grade security — Hologres isn't some hobby project. It's built for reliability with proper access controls and high availability.

OpenClaw Native vs. This Setup

What Matters OpenClaw Default With Hologres + Mem0
Where data lives Local SQLite/LanceDB Hologres (cloud data warehouse)
Persistence Hope your hard drive doesn't fail Proper cloud storage with redundancy
Sync across devices Nope Yep
Vector search It works HGraph index — fast even at scale
How much data Whatever fits locally Petabytes, seriously
Write speed Local writes Milliseconds to cloud
SQL support Basic Full PostgreSQL
Full-text search Bare bones Tantivy — actually fast

What Makes HGraph Worth It

  • Fast searches — Handles both approximate and exact lookups, optimized for when you've got tons of vectors.
  • Mix and match — Index vectors alongside regular data. Useful when your queries get complicated.
  • Save space — Vector quantization compresses things down without killing accuracy.

Setting It Up

Pro tip: You can actually use OpenClaw itself to walk through these steps.

Step 1: Spin Up a Hologres Database

Create an instance, jump into your Hologres instance and create a database:

CREATE DATABASE openclaw_mem0;

Step 2: Install the Plugin

In your OpenClaw environment:

openclaw plugins install @hologres/openclaw-mem0

Step 3: Wire Things Up

Pop open ~/.openclaw/openclaw.json and add your Hologres details:

{
  "openclaw-mem0": {
    "enabled": true,
    "config": {
      "mode": "open-source",
      "userId": "<YOUR_NAME>",
      "oss": {
        "llm": {
          "provider": "openai",
          "config": {
            "baseURL": "https://dashscope.aliyuncs.com/compatible-mode/v1",
            "apiKey": "<YOUR_DASHSCOPE_API_KEY>",
            "model": "qwen-plus"
          }
        },
        "embedder": {
          "provider": "openai",
          "config": {
            "baseURL": "https://dashscope.aliyuncs.com/compatible-mode/v1",
            "apiKey": "<YOUR_DASHSCOPE_API_KEY>",
            "model": "text-embedding-v4",
            "embeddingDims": 1024
          }
        },
        "vectorStore": {
          "provider": "hologres",
          "config": {
            "host": "<hologres-url>",
            "port": 80,
            "dbname": "openclaw_mem0",#please create this db first
            "user": "<user>",
            "password": "<password>",
            "embeddingModelDims": 1024
          }
        }
      }
    }
  }
}

What goes where:

Placeholder What to put
<YOUR_NAME> Your user ID — keeps your memories separate from others
<YOUR_DASHSCOPE_API_KEY> Your Model Studio key for the LLM and embeddings.Check instruction here.
<YOUR_HOLOGRES_HOST> Your Hologres instance endpoint
<YOUR_HOLOGRES_USER> Database username
<YOUR_HOLOGRES_PASSWORD> Database password

Step 4: Restart your OpenClaw

Testing It Out

Does it remember?

  1. Tell it something: "I'm Alex, remind me about my standup meeting every Tuesday at 10am."
  2. Wait for the acknowledgment.
  3. Ask: "What do you know about me?"
  4. Check if it remembers your name.

Peeking at the data

Want to see what's stored? Query Hologres directly:

SELECT id, vector, payload
FROM memories 
LIMIT 10;

Quick Questions

Q: What is Mem0? Mem0 is an open-source memory layer for AI that handles extracting, vectorizing, storing, and retrieving conversational memories.

Q: How does Hologres help with AI memory? Hologres provides cloud-based vector storage with HGraph indexing for fast similarity search across millions of memories.

Q: Can I sync OpenClaw across devices? Yes! With Hologres as the backend, your conversational AI remembers you across devices automatically.

Q: Is there a cost? Pricing varies based on usage. Check Alibaba Cloud for currentHologres pricingdetails.

Wrapping Up

Here's the thing: OpenClaw with local storage is fine for tinkering. But when you add Hologres as the memory backend, you get something you can actually rely on. Your conversational AI remembers you across devices, the data sticks around, and you get enterprise-grade reliability. If you're serious about your AI assistant setup, this is the way to go.
