Hey everyone, I’ve been exploring Vectorize for my product in a multi-tenant setup where each tenant gets their own index chunk via namespaces. Because of the worker binding count limit (and lack of dynamic creation), I went with the REST API approach.

But I recently discovered that Cloudflare rate limits HTTP requests (1,000 per 5 minutes), which makes me wonder how Vectorize is supposed to be used effectively in a multi-tenant setup.

I’m confused because Cloudflare advertises 50k indexes per account, but in practice this doesn’t seem possible due to the worker binding limit + request rate limits. Feeling a bit stuck and frustrated—what’s the recommended approach here?

Not sure what I'm doing wrong, but each time I try to query for embeddings with metadata filters, it gives me no results, even if the embeddings are the same. First image is the result without filters (see the userId metadata key?)

This is my code:

export const search = base
    .route({ method: 'POST', path: '/ai/vectors/search' })
    .input(
        z.object({
            embeddings: z.array(z.number()),

            filter: z.record(z.string(), z.any()).optional(),
        })
    )
    .output(vectorizeMatchesSchema)
    .handler(async ({ input, context }) => {
        const options: VectorizeQueryOptions = {
            returnMetadata: true,

        if (input.filter) {
            options.filter = input.filter;

        const results = await context.env.VECTORIZE.query(input.embeddings, options);
        return vectorizeMatchesSchema.parse(results);
    });

Is there a way to delete a namespace?

C

cosbgn•11/11/25, 8:57 AM

e.g. I have one namespace per customer. When a customer delete its account, should I query all vectors and use deleteById or there is a way to simply delete a namespace?

C

cosbgn•11/11/25, 8:58 AM

and even if I use deleteById, will I then have a hunging empty namespace which uses one of my 5000 max namespace quotas or vectorize will automatically free it?

C

cosbgn•11/11/25, 8:59 AM

So I just read the message above and

deleteById

deleteById

deleteById

deleteById seems the way, but will the empty namespace still count against the 5K quota?

Has anyone experienced a vector count mismatch with LangChain + Cloudflare Vectorize?
I'm noticing a discrepancy where my D1 document count doesn't match my Vectorize index. For example, I have 12 raw documents in D1, but 48 vectors in Vectorize (4x the amount). Also I am seeing this discrepency in other indices where the vectors are 4x the raw chunks in D1.

Have others run into this issue? Any insights on what might be causing this would be appreciated!
