Yup, that's my case. Do you see any advantages/disadvantages to using one big index with all user vectors + metadata filtering by a user id vs. one index per user?

Matt Silverlock•10/5/23, 11:30 AM

It will depend on your index size. If the count of vectors per user is very small, and will remain so, a larger single index will remain “hot”

Zak @ insertchat.comOP•10/5/23, 11:31 AM

Oh I see, there is a notion of hot/cold storage involved. What's your definition of small? Millions? Tens of millions? 1 billion?

Matt Silverlock•10/5/23, 11:33 AM

per user or per index? Small would be thousands per user - over hundreds of thousands of users -> an index in the millions.

Zak @ insertchat.comOP•10/5/23, 11:34 AM

I don't have more then a million vector per user

Matt Silverlock•10/5/23, 11:34 AM

To step back a second: it really doesn’t matter that much, and it probably doesn’t make a lot of sense to over engineer this right now

Zak @ insertchat.comOP•10/5/23, 11:34 AM

The total in my db right now is between 5 and 10 millions vectors

Matt Silverlock•10/5/23, 11:35 AM

That’s fine.

Matt Silverlock•10/5/23, 11:36 AM

Write your raw embeddings to R2. If you want to change your approach, it’s much easier to repopulate an index vs a traditional RDBMS

Zak @ insertchat.comOP•10/5/23, 11:39 AM

Will dump a few million vectors to Vectorize once we have filtering to see how it performs with a user id filter, if it's good then it's a go for production, and will see if we change it later to multiple indexes

Zak @ insertchat.comOP•10/5/23, 12:35 PM

Can we also expect a way to CRUD a vector (row) directly by its id/uid?

Andrew Mayne•10/6/23, 12:07 AM

Hey folks! Two questions:

1. Is there some knack to saving meta data? Everything else saves in this example except the metadata:

const embedding = await getOpenAIEmbedding(description, env.OPENAI_KEY);
await env.VECTORIZE.upsert([{ id: promptId, values: embedding, metadata:{ title:"Updated title", description: "Description"} }]);

console.log("Item vector added:", { title: title, description: description })

2. Everytime I update from the CLI my vector binding are erased. Adding this to the TOML doesn't seem to help:

vectorize = [
{ binding = "VECTORIZE", index_name = "my-index" }
]

Or:

[[vectorize]]
binding = "VECTORIZE"
index_name = "my-index"

Old Man Maker•10/6/23, 2:48 AM

Keep in mind that metadata as a type may change in future if filtering by metadata is added.

At the moment, this is how I create it:

//I defined a new object type for the metadata - MetadataSchema 
let newMetaData:MetadataSchema ={
    d1Key: keyValue,
    prjRef: projectRef,
    accRef: accountRef,
    parentRef:parentRef
}

//Stuff the object in there
const metaRecord:Record<string,VectorizeVectorMetadata>= { 
    "data": JSON.stringify(newMetaData)
};

//Add to the vector
let tempVec:VectorizeVector ={
    id:id,
    values: data[0], //the embeddings
    namespace:<The Namespace>,
    metadata:metaRecord
}

//I defined a new object type for the metadata - MetadataSchema 
let newMetaData:MetadataSchema ={
    d1Key: keyValue,
    prjRef: projectRef,
    accRef: accountRef,
    parentRef:parentRef
}

//Stuff the object in there
const metaRecord:Record<string,VectorizeVectorMetadata>= { 
    "data": JSON.stringify(newMetaData)
};

//Add to the vector
let tempVec:VectorizeVector ={
    id:id,
    values: data[0], //the embeddings
    namespace:<The Namespace>,
    metadata:metaRecord
}

npx wrangler deploy works though.

Oh no, I just thought that had a "free layer" :c

-> I figure it out, it work just for paid worker planes, for now. And CF is planning to launch a free tier soon.

So, someone know when is It planed to come?

charl.dev•10/10/23, 8:47 AM

I need some info around the security due diligence etc around vectorize, like is the data encrypted, is there encryption at rest, GDPR, CCPA, HIPAA compliance.

Is there a doc or something we can give to our infosec guys?

kian•10/10/23, 8:50 AM

The information generic to Cloudflare is likely all that is available so far - https://www.cloudflare.com/en-gb/trust-hub/

Assuming that Vectorize is built on top of the existing primitives like Workers, Durable Objects and Workers KV then there will be information that already covers those.

Generally all of Cloudflare's offerings are covered under Standard Contractual Clauses with regards to GDPR.

not sure if you guys have any guidance on optimal chunk size, think langchain textsplitter defaults to 1000 with 200 overlap. Some supabase pgvector articles kinda saying the same, 500 - 1000 chars..

Old Man Maker•10/10/23, 6:36 PM

Just remember that your chunk size is going to be limited by the input token max on the embedding model if you're using CF hosted models for that - generally, it appears to be around 170 words based on 1-3 tokens per word:
