We updated MyScale free knowledge base, where you can try your RAG with
36 million paragraphs from wikipedia and 2 million paragraphs from
ArXiv.

The pod has two tables
```sql
CREATE TABLE default.ChatArXiv (
    `abstract` String, 
    `id` String, 
    `vector` Array(Float32), 
    `metadata` Object('JSON'), 
    `pubdate` DateTime,
    `title` String,
    `categories` Array(String),
    `authors` Array(String), 
    `comment` String,
    `primary_category` String,
    VECTOR INDEX vec_idx vector TYPE MSTG('metric_type=Cosine'), 
    CONSTRAINT vec_len CHECK length(vector) = 768) 
ENGINE = ReplacingMergeTree ORDER BY id;

CREATE TABLE wiki.Wikipedia (
    `id` String, 
    `title` String, 
    `text` String,
    `url` String,
    `wiki_id` UInt64,
    `views` Float32,
    `paragraph_id` UInt64,
    `langs` UInt32, 
    `emb` Array(Float32), 
    VECTOR INDEX emb_idx emb TYPE MSTG('metric_type=Cosine'), 
    CONSTRAINT emb_len CHECK length(emb) = 768) 
ENGINE = ReplacingMergeTree ORDER BY id;
```

You can connect those two tables using credentials below (just the same
to the old one)
URL: `msc-4a9e710a.us-east-1.aws.staging.myscale.cloud`
Port: `443`
Username: `chatdata`
Password: `myscale_rocks`

It's FREE and you can also use it with

... and also LangChain!
