sorry for the typo i did {"path": {"$ne": null}, } and the path prop is not indexed

Quick question

Why do we need to create metadata index and even if we have to create, why only 1 key at a time and upto 10 index is the limit? While upstash allows to filter on metadata normally on all metadata
Can we also expect glob and more type of searches operators along with eq and neq

Like : contains , IN, not in, glob, pattern match, and , or etc

can we also have hybrid search like a cosine similarity search with Full text search as well for better search in future?

Hey! Whats the limit on insert/upsert.
for some reasons, my vector inserts/upsers have stoped at 128.04k vectors.
In dev, in another vectorize database, everything is working fine. Is there any hidden limit we dont know about???

thousandmiles•11/5/24, 1:23 AM

I've been browsing through messages in the past and documentations on vectorize, looks like now it's a great time to jump in, considering the beta release of workflow as well. though my concern is full RAG pipeline still needs a long way to go, so I'd prefer develop locally using llamaindex+chromadb(or equivalent)+litellm(embedding, inference, rerank, whisper, etc) first, before switching to cloudflare edge side completely, which I do need at a certain point because the product I am building requires global coverage.

may I ask guy who already had previous experiences here, that, is this a viable plan, or anything I should keep in mind for choosing tech stack or develop or doing gitops? thanks a million!

Is supporting arrays with metadata filtering on the roadmap? I'm migrating a v1 index to v2, and looking at adding a metadata index while I'm at it, but my metadata has string array properties. According to the docs this isn't possible now, but will it be in the near future? If not, I'll need to rethink how my metadata is stored before the migration.

How can I see what vectors I have in my index? I checked the commands I could run, and none mentioned showing the vectors I got in my index. I want to be able to delete and test stuff before I run the actual thing. Any guidance would be appreciated.

Are there any tips and tricks to improve query performance against Vectorize?

We make use of (per-project) namespaces for limiting the scope of similarity searches, and are seeing very slow performance on initial query against a namespace, and subsequent queries are much faster. One example has roughly 100 vectors and is taking ~3s for first query vs ~150ms for subsequent queries. Are cold-starts a thing with Vectorize?

Hello, Quick question, I get really slow response times in Vectorise. Like seconds of response time. My code is very simple, so nothing else should be slowing it down. I am in Greece btw, so not sure if that plays a role. I get the same speeds when deploying the worker.

                    },
                });
            } catch (error) {
                console.log(error);
            }

Summary of the fixes:

I enclosed the object being passed to the Vectorize insert operation in square brackets. This is needed because the insert function requires the input to be of an Array type.
I converted the id from 1 to '1'. This is needed because Vectorize vector identifiers need to be of a String type.

Feel free to reach out if you need additional support for Vectorize!

Thank you so much, I spent 6 hours trying to figure out what the issue is and it turns out to be the brackets, I also remember trying stringifying the id but it still never worked.

Happens to the best of us, I am glad we could help you out with this! Something that helps us when we develop Worker code is to setup the Worker locally as an npm project. Then you can load the project into your preferred IDE which would almost certainly display relevant packages and method signatures from

node_modules. This project code can also be pushed to your preferred Version Control System if it is a collaborative project. You can refer to https://developers.cloudflare.com/vectorize/get-started/embeddings/ for an example on setting up the project from scratch.

Thank you, I had it working on another test worker that I was playing around with and when it came to production, I got stuck at this because I didn't notice the brackets

Is it possible to insert 5000 at the same time using insert function? As far as I know it's possible to do it through embeddings.ndjson file, but would 5000 work or is there another limit?

The current batch size limit is 1000 vectors, when you insert/upsert using a Worker: https://developers.cloudflare.com/vectorize/platform/limits/. A higher limit of 5000 vectors is available for inserts/upserts via the HTTP API.

Hi @garvitg , I got question regarding the workers ai and vectorize, I have an app running Resnet50 to vectorize image, I'm planning to switch over to cloudflare since you guys support Resnet50, however, I saw the limitiations of the Vectorize it says it has maximum dimensions per vector 1536 dimensions, which is not high enough for my app since it generate 2048 dimensions using Resnet50, any idea how can I reduce the dimensions that is generated from Resnet50?

I'm really new to this field, so any help would be awesome, thanks!

is it possible to load stuff into a prod vectorize index from the local machine? or is the data running in the miniflare / simulator only?

Hi everyone. I wonder if someone could help me fill some gaps in my knowledge relating to using Vectorize (and vectorisation generally) to help with AI data analysis on potentially large datasets.

Without Vectorize, I can send data to an LLM for analysis/categorisation etc., but I'm of course limited by tokens as to how much data I can send. I have done some reading and I understand that getting my data into a Vectorize DB, then querying that as a preliminary step to sending data off to the LLM for analysis, might be the answer here.

But I'm hazy on the exact steps/rationale. Specifically, how does this help limit the amount of data I ultimately send to the LLM? Is the idea that Vectorize reduces it to a subset, so duplicates or near-duplicates are merged/omitted, or...? (Sorry for the long message - just looking for some high-level guidance!)

So the idea with RAG is this:

you embed all your documents and store them in a vector DB (vectorize or otherwise)
when a user question comes in, you embed the user question
you do a search in the vector DB for "top <n> items" where
```
n
```
n
```
n
```
n
is 3, or 5, or 10, or higher depending on your use-case
you give the results to the LLM along with the query

The idea is that, because embeddings between related items are similar, when you query the vector DB with the embedding of the user question, you're likely to get back things in the vector DB related to the user question. Then you give that to the LLM to actually answer the question based on the gathered knowledge.

Mitya•12/4/24, 3:53 PM

Thank you, that's really helpful. So this model depends on a particular question as a filter, and is less useful if, say, I simply want to run sentiment analysis on 100,000 user messages. Right?

I

Isaac McFadyenOP•12/4/24, 3:55 PM

So you can definitely run sentiment analysis using an LLM, but you wouldn't really need a RAG pipeline for that unless your sentiment depends on some external knowledge you want to give the LLM.

M

Mitya•12/4/24, 3:56 PM

Right. My thinking for introducing RAG was to get round the issue of there being a limit on how much data I can send to an LLM in one go. Perhaps that requires a different solution i.e. piecemeal analysis on 1000 messages at a time and then derive an average of all the sentiments or something.

I

Isaac McFadyenOP•12/4/24, 3:57 PM

Do the sentiments relate to one another?

I

Isaac McFadyenOP•12/4/24, 3:57 PM

As in, usually you'd only send a few messages at a time, but do you need the context of all the messages at once to derive overall sentiment?

M

Mitya•12/4/24, 3:59 PM

Probably yes, because the user messages are written freely. A real example: Users might feed back to the question "What do you think of our show?". And we'd like to do two things: 1) give sentiment analysis e.g. people are mostly happy; 2) have the LLM give suggestions e.g. "People want more matinée shows"

I

Isaac McFadyenOP•12/4/24, 3:59 PM

I see. So usually sending all the messages at once is going to significantly degrade your result and cost a lot.

I

Isaac McFadyenOP•12/4/24, 4:00 PM

Instead you'd analyze each message individually, and then do what you want with the statistics.

I

Isaac McFadyenOP•12/4/24, 4:00 PM

That also allows different kinds of reporting: "10 users disliked it but the majority thought it was great" or "1% of users gave <x> feedback about the show" etc.

Whereas your initial question wasn't quoted, meaning it would be actual `null`
