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`
