I have 1536 dimension openai embeddings and I can't insert 284 of them, but it works if I only insert the first up to 100 vectors. 101 doesn't work.

I looked up the limitations and didn't see anything relevant. Is this a bug?

Update: I implemented chunking and now all the request fail (they have 90 vectors each, so I have like 4 of them). If I try a few times, sometimes several of the 4 request succeed, but never all and it's not reliably of course

Update 2: Still trying to triangulate the issue. Tested by slicing only the first 3 dimensions and then I can insert all at once without a problem or batch them into 4 batches without a problem. Weird

Update 3: Batching into maxSize 10 batches (29 of them) did work on all 29 insert requests. Is there any metadata or index name limit per batch maybe?

Do you have metadata or index names that exceed the limits? Are you positive they don’t?

divby0OP•11/27/23, 3:13 PM

Otherwise batching them into 29 individual batches wouldn't have 100% success rate

divby0OP•11/27/23, 3:13 PM

Let me programmatically check again

divby0OP•11/27/23, 3:15 PM

id is a uuid-v4 (36 characters)
and the metadata is always below 8000 characters for all 284 vectors

Matt Silverlock•11/27/23, 4:15 PM

How are you counting metadata length? The limit is enforced on all bytes (keys, etc included), not just values. Our error handling needs to be better here but would be good to rule that out.

deo time•11/27/23, 4:31 PM

I had to write a helper that would batch them into groups of 100 as well as retry if a 500 error happened, worked for the most part

deo time•11/27/23, 4:34 PM

If you're inserting a lot though itll take quite a while

divby0OP•11/27/23, 6:32 PM

Yes, I have a static key (and only one). It's basically {"content":"..."}{"content":"..."} with the ...... being less than 8'000 for all elements. Which should guarantee that it's less than 10KiB, right?

divby0OP•11/27/23, 6:46 PM

Also it works when I batch the individual vectors into small enough amounts so this is also a proof that the metadata is not too big (or any other single field)

divby0OP•11/27/23, 6:47 PM

I already was a bit mad that I need to write batching, but I'd hate to write a retry mechanism for inserting some vectors.

But many thanks, this might be my only option until they support the bindings version for pages functions. Which can't be too far away I guess

divby0OP•11/28/23, 10:28 AM

I am getting error code 2007. What does that mean and where can I look it up? There must be a list of error codes somewhere, otherwise you guys wouldn't have exposed one, right?

divby0OP•11/28/23, 10:30 AM

If I recall correct, the reported error improvements that are coming very soon are still not there after 2 months. At least I happened to send the wrong amoutn of dimensions yesterday as well and it showed me a non-useful internal error.

divby0OP•11/28/23, 10:47 AM

I changed nothing and now, 18mins later the same request went through. I didn't redeploy (so env vars haven't changed), I merely had different vectors that were sent maybe (same openai 1536 embeddings, just for different content).

I am not sure if I am supposed to write so much here, but I'd figure the cloudflare team would be interested in seeing exactly what's not working.

Update: it has failed a few times again and now works a few times again. Not sure what I should learn from this

Jerome•11/28/23, 11:34 AM

Code 2007 is an error whose internals are not exposed; for an upsert it means that there were issues while trying to make the change durable. We are seeing this elevated error rate when write rate on an index reaches some threshold. This is something we are aware of, and we are working on improving the situation.

Jerome•11/28/23, 11:36 AM

Thank you for reporting!

divby0OP•11/28/23, 11:37 AM

This specific issue was with the query endpoint in fact. Still something you have on the radar?

Jerome•11/28/23, 11:38 AM

Yes, for query operations it means that the durable storage access failed while reading, despite retries

divby0OP•11/28/23, 11:38 AM

I see, okay. So if you guys have those things on your radar and we can expect improvements, that's all I can ask for. I just thought I may be the only one experiencing this and there is a specific bug causing this for me

Jerome•11/28/23, 11:38 AM

Hello! I'm having some issues with Vectorize's query function.
When I run await env.<INDEX>.query(vector, { topK: 1})await env.<INDEX>.query(vector, { topK: 1}), in some cases it simply fails and returns the following error message: TypeError: Cannot read properties of undefined (reading '0')TypeError: Cannot read properties of undefined (reading '0')
It's completely unpredictable, sometimes it works perfectly after a couple of calls, sometimes it fails on the very first one. The reading '0'reading '0' isn't constant either, sometimes the number is different, and different userQueries result in different numbers.
Here is the code for the function

export async function getEmbedResponse(env: Environment, userQuery: string, data: string[]): Promise<{ score: number, result: string }> {
  const ai = new Ai(env.AI)

  const queryVector: EmbeddingResponse = await ai.run('@cf/baai/bge-base-en-v1.5', {
    text: [userQuery],
  })

  let matches = await env.<INDEX>.query(queryVector.data[0], { topK: 1 })

  const embedAiResponse = { score: matches.matches[0].score, result: data[parseInt(matches.matches[0].vectorId)] }

  return embedAiResponse
}

export async function getEmbedResponse(env: Environment, userQuery: string, data: string[]): Promise<{ score: number, result: string }> {
  const ai = new Ai(env.AI)

  const queryVector: EmbeddingResponse = await ai.run('@cf/baai/bge-base-en-v1.5', {
    text: [userQuery],
  })

  let matches = await env.<INDEX>.query(queryVector.data[0], { topK: 1 })

  const embedAiResponse = { score: matches.matches[0].score, result: data[parseInt(matches.matches[0].vectorId)] }

  return embedAiResponse
}

EmbeddingResponse is an interface based on the examples on the website

interface EmbeddingResponse {
    shape: number[];
    data: number[][];
}

interface EmbeddingResponse {
    shape: number[];
    data: number[][];
}

Esked•11/29/23, 5:58 PM

I run the vector upserting before calling this function

Esked•11/29/23, 8:46 PM

I can see the error message after the query call too

Soon! Ideally before the next holiday period. Prioritizing some stability/scalability work and metadata filtering first, but should be a very fast follow.

chand1012•11/30/23, 7:57 PM

Is there a way when querying vectorize to filter by ids as well as the vector themselves? You mentioned metadata filtering, I guess that's pretty close to what I'm looking for. I formatted my IDs in such a way where they contain both an index and the ID of them in my D1 database.

huw•12/1/23, 3:24 AM

Yeah, this would be supported by metadata filtering or even namespaces. If you only ever want to filter on one of your ‘indices’ at a time, you could totally use namespaces today; for anything more complex you should wait for metadata filtering

chand1012•12/1/23, 3:56 PM

Metadata filtering would be fine, do you have an ETA on when this feature will be ready?

chand1012•12/1/23, 4:16 PM

My use case for either feature is I'd like to have one vector index for all the items in a database table, when some of the content from the table may be from both user A and user B, and I only want to query for user A as they're the one making the request.

steyblind•12/1/23, 5:08 PM

Not sure if I missed something here:

1. metadata "included in results" was released
2. on an existing worker, I updated the compatibility date
3. on an existing vectorize db there was no change
4. I updated my worker to use the includeMetadataincludeMetadata param

and... no metadata returned?
