Cloudflare Vectorize Support · Issue #14179 · langchain-ai/langchain

Feature request Looks like it should be doable to have Cloudflare Vectorize support, as there's a HTTP API for Vectorize. https://developers.cloudflare.com/api/operations/vectorize-list-vectori...

if anybody official wants to chime in on the ticket to confirm if my assumptions are wrong/right

Oh I know, I just want it to use Vectorize in Python too!

Ah, sorry, misread. You should contribute it

It'll be in the URL when you're on the dashboard, but otherwise you can find it on the sidebar as the docs say.

whats the expected error when we exceed # of vec, namespace per index

hopfully the hard limit on namespace will be lifted post beta

After connecting to Vectorize, there is no results data when requesting a D1 query.
Previously, it worked fine.
In the dashboard, the number of query requests is increasing.
Probably a bug.

MMatt Silverlock Per _index_

Yep, the per index part is important

Vy•12/8/23, 3:29 PM

With open beta product today, we can't support that large of an index. However, it's something we're working on! Are you often (1) searching across all 5M vectors or (2) search space is smaller but used to operating a single index?

huw•12/11/23, 11:51 PM

Hello! Is there a limit on the maximum number of IDs for getByIdsgetByIds and deleteByIdsdeleteByIds? I am scheduling a bulk delete and want to know if I should chunk it, or if that limit is well above the memory size of a Worker. (EDIT for searchers: Limit is 20)

yevgen•12/12/23, 11:08 AM

Hi Bhanu, Eng manager here. Based on the info you provided I suggest splitting your 5M vectors index into smaller indexes per customer id. Let me know if 100 indexes per account is sufficient for you (we can bump this limit if necessary). You will get much better performance searching in smaller indexes. We are working hard to bump vectors per index limit, we don't have ETA for this to be ready though.

huw•12/12/23, 11:15 PM

This would also be more reasonable if there was a way to programatically create Workers bindings for indices, but you have to use

wrangler.toml

wrangler.toml

right now which hard-codes your limit

huw•12/12/23, 11:16 PM

I’m not sure about the specifics—you can use API calls to create and query indices dynamically, sure, but aren’t those API calls slower?

huw•12/13/23, 9:41 AM

Are pages bindings here yet? The API doesn't support delete so I can't really use it. Gotta wait for pages bindings :/

hey - we started to get a strange 502 error from search API -

Hey folks, love the work on the AI stuff! Just wanted to drop in to chime in that I would love it for the limits on Vectorize index to be way higher, to the tune of a couple of indices per user of my app. That's all!

for survey purposes, what limit would fit your use case?

JJerome for survey purposes, what limit would fit your use case?

xeon06•12/14/23, 8:56 PM

I don't want to give a number because it would scale with the number of users my app has, e.g. I need to be able to make vector searches against documents belonging only to a single user.

Even if it was 10,000, then what do I do at 10k users!

xeon06•12/14/23, 9:00 PM

There's a world where I can filter post search, but that doesn't seem inefficient and probably severely limited by the topKtopK limit

huw•12/14/23, 11:59 PM

The in between here is namespaces, right now if you maximally used indices & namespaces you could support 100k users

huw•12/15/23, 12:00 AM

tbh it’s not really clear whether a user-segmented app is supposed to use separate indices or separate namespaces right now—only except that namespaces have the advantage of using proper service bindings but if you go for

indices you’d have to use the API
