1000 namespaces for now it would be enough to have one per user, but that can eventually be increase

1000 namespaces for now it would be enough to have one per user, but that can eventually be increased, right?

cosbgnOP•9/9/24, 1:29 PM

Also, is there any restriction on saving the original text in the metadata? It would save me an extra call to D1

cosbgnOP•9/9/24, 1:30 PM

10KiB of metadata is enough to store most text

cosbgnOP•9/9/24, 1:31 PM

all of it actually + some ids and some other small info

yevgen•9/9/24, 5:32 PM

yes, it could be increased.

Hi, when trying to get vector values the Vectorize API docs say

values

values

is "an array of number, Float32Array, or Float64Array as the vector embedding itself."

Can someone tell me what actually determines which one of these types the vector is?

Jerome•9/11/24, 5:57 PM

Hi! I believe you're refering to https://developers.cloudflare.com/vectorize/best-practices/query-vectors/; the format you use to query your DB through a binding can be either of these, it'll be interpreted the same way, as a floating point number array. You also don't have to use the type that matches the one you used when inserting/upserting, all number formats are interoperable for insert/upsert and query.

ac•9/11/24, 8:31 PM

Thanks, but I'm talking about the return value. It seems like there are instances when it is Float32Array or Float64Array instead of number[], but I'm trying to determine how to know which it will be.

We saw intermittent issues with one of the service instances running in our Core datacenter. It has resolved now.

cosbgnOP•9/15/24, 4:07 PM

Any way to filter metadata as array includes?

In my use case I have some files and they have tags like ["books", "work"], etc these tags are set by the users and I don't know them in advance.

Ideally I would be able to query embeddings only for "work" or only for "books" ]

Any way to delete a namespace and all the vectors inside it via rest API? doesn't seem to be documented

charl.dev•9/16/24, 8:32 PM

Is setting a ttl on a vector entry, similar to kv on the cards?

Have items I want to clear out like 3 months after creation. Can do like a nightly purge but would be a great feature IMO

I've been deleting through "wrangler vectorize delete <index_name>"

though I'm running into an issue when trying to create a new index under the same name

it gets deleted off my dashboard but I get this error when creating a duplicate index. Not sure how to fully remove it and its history

chronark•9/18/24, 8:47 AM

is there a way to clear data in an index in the UI?
I can't see any and the docs aren't helping either

Sunny•9/18/24, 3:28 PM

I think you can only delete elements through the wrangler cli, and it’s only element by element, reference by id

Sunny•9/18/24, 3:28 PM

Otherwise, again through cli, you delete the whole index and make a new one

Hi all, when I delete an index, and try to create it with the same name through the API, I get

{
    "result": null,
    "success": false,
    "errors": [{
        "code": 3005,
        "message": "vectorize.index.deleted - Index name \"your_index_name\""
    }],
    "messages": []
}

    }],

Is that by design? Is there a timelimit that it'll be purged on the backend?

Eric•9/25/24, 7:05 AM

Also, say I want to have multiple collections of data be indexed, but such data is completely unrelated to each other. Is it better to:

Create a single index and have it search the embeddings by namespace? (Also: Is the intended usage for namespaces specifically for file/data types?)
Store grouping information in the metadata, and have it query by the metadata? I doubt this one, since the collections are intended to be completely unrelated.
Create new indexes for each collection of data?

Jerome•9/25/24, 9:34 AM

1 index per collection seems the way to go if you will not want to run queries spanning several collections, and the number of collections is small and constant (as you'll want to bind against them in your worker, which is a manual operation).

Otherwise, one index with logic partitioning of the collections; namespace is the designated way to achieve this (but metadata would also work as you pointed out). With this approach (1 index with logic partitioning) you need to make sure however that your collections all use vectors that are the same dimension, indexed and queried with the same distance metric, and ideally from the same source (the same LLM for instance) to ensure consistency in the vector data, for best indexing accuracy.

Rihan•9/25/24, 1:10 PM

Is there a planned way to empty a Vectorize index? My use case is resetting a preview environment's index. If not, the only way forward I see is recreating with a random string suffix.

Rihan•9/25/24, 3:03 PM

Furthermore would it be possible to support name reuse in the future?

RRihan Furthermore would it be possible to support name reuse in the future?

Jerome•9/25/24, 3:42 PM

Yes, we are aware this is an inconvenience and supporting index name reuse after deletion is on the roadmap, no shipping date yet

Eric•9/25/24, 11:25 PM

Gotcha. Thanks for the info!

Eric•9/26/24, 3:32 AM

A little follow up; I still don't quite understand the design for multi-collection dynamic data storage. Binding an index to a worker is a manual operation so dynamically created indexes aren't possible. This infers that having multiple indexes exist only for the purpose of different dimension sizes/metrics/embedding functions (since these are determined at creation time, and are constant) OR unless the data stored is also constant.

Say I have a user in my application with his/her own collection of data and they want to put it into an index dynamically. This must be done within a single index that all users share (separated by namespace for each user). Looking at the limits here:
https://developers.cloudflare.com/vectorize/platform/limits/
"Maximum vectors per index" shows a max of 5mil for the beta. Say the limit grows to 100mil- although 100mil embeddings is a lot for a single user, this won't scale well if I enable my users to upload data, forced to upload to a single index.

The (current beta) limit for number of indexes is 100. Say in the future we're able to bind indexes to workers dynamically. That still won't suffice for a user base even if that number grows to 10k or more.

In order to properly handle dynamic scaling, I could create all 100 possible indexes now, all empty, and use them as overflow space once the current index fills up. Coding this containerization algo would suck and I doubt that's the intended purpose.

I get the impression that uploading data and initializing indexes is a constant operation. I'm designing an application now so any advice on how to properly design my architecture for the future would help! @Jerome

Eric•9/26/24, 3:37 AM

Currently I'll be limited by:

100 users max where each index name can only be used once OR
5 mil embeddings total for the application OR
My coding ability to whip up a containerization algo, then limited by 100 indexes * 5mil vectors (in beta i know, but still)

I guess my question boils down to- how should I design my application such that it scales dynamically once beta is over? Thank you for being informative so far

Yyevgen yes, Q1 2025 we plan to ship support for Vectorize dynamic bindings.

Rihan•9/26/24, 9:49 AM

@Eric Vectorize dynamic bindings are coming hopefully in Q1. I believe Cloudflare can increase the number of indexes limit on an account basis too.
