Hello, I have a question. It seems the indexing process takes few seconds. When we insert data, we get a mutation id. Is there any way to check against the mutation id if that batch got indexed or not?

beingmudit [WePlayDOS]•2/9/25, 8:42 PM

Damn! @Bob I joined this discord just to ask the same questions. Interesting that this is not just me experienceing indexing latency.

beingmudit [WePlayDOS]•2/9/25, 8:43 PM

Hey CF team!

We're building with Vectorize and noticed some interesting behavior around indexing latency and consistency. Here's what we're observing:

Indexing Latency:
Create index -> Success (immediate)
Add 2 vectors -> Success (immediate)
Search vectors -> No results for ~9 seconds
Search attempt timeline:
- 0s: No results
- 3s: No results
- 6s: No results
- 9s: Finally get results
Deletion Consistency:
After vectors are searchable
Delete vector "vec1" -> Success
Immediate search still returns both vectors including the deleted one
Subsequent searches also return the deleted vector

Test Case Details:

Index dimension: 32
Two simple test vectors:
- vec1: Array(32).fill(0.1)
- vec2: Array(32).fill(0.2)
Query vector: Array(32).fill(0.15)

Questions:

Is this expected latency for indexing?
Are there any best practices for handling the indexing delay?
Should deleted vectors remain searchable? If not, is there a known delay before deletions are reflected?
Are there any configuration options we should be using to optimize this?

Full test code available if needed. Thanks for any insights/help/

Utkarsh Saxena•2/10/25, 5:23 AM

I think, You can check with getByIDs, as the insertion in index is async now in v2.

beingmudit [WePlayDOS]•2/10/25, 7:23 AM

Can you share the docs where it mentions something related to this? This seems like a big limitations given other services are super duper fast.

Utkarsh Saxena•2/10/25, 8:13 AM

Sure, You can see this: https://developers.cloudflare.com/vectorize/reference/transition-vectorize-legacy/#notable-changes
It is mentioned it takes few seconds to reflect and is asynchronous now.

Jerome•2/10/25, 9:44 PM

Hi! yes the updates are processed asynchronously, and can take some time before being reflected in queries; 6 to 9s processing loop sounds like normal operation.

beingmudit [WePlayDOS]•2/10/25, 9:48 PM

Hey Jerome, thanks for getting back. Do you think if it makes sense to have it documented somewhere in the public facing docs? This async behaviour is really tricky to find.
Also, Do you know if other services do have similar latencies?

Jerome•2/10/25, 9:52 PM

It's in the doc clearly stated for insert (same for upsert):

So I make an index.
I delete the index.
I make an index with same id.
verify new index info
I try to upsert vector - fails saying index is deleted
I retry the exact same upsert api request (no change) - success

beingmudit [WePlayDOS]•2/14/25, 6:18 AM

Yes because the operations are async. When you get the response. it is just an ack not the actual operation.

Victor•2/15/25, 1:49 AM

I've had it happen even as far as an insert 24h after making the index again. And I get index info after creating it and verify it was created correctly

I've also checked and it looks like my index isn't there anymore, does anyone know why this is happening?

I also get the error code vectorize.index.deletedvectorize.index.deleted when trying to get it via cli, so it looks like it was just forcefully deleted somehow?

noad.eth•3/8/25, 12:39 PM

Hi. I just started using Vectorize this week. Really liking it so far. Nice and simple.

For inserting/upserting vectors using the REST API (or Typescript SDK), it would be nice if the request body could also accept an array of vector objects.

When using the TS package, if I set the body value to be the ndjson string, I was getting a "failed to parse" error. I found I had to wrap the ndjson in a Buffer.from()Buffer.from() to get it to work, but had to ignore a TS error since body is typed as a

Nick•3/25/25, 9:19 PM

Hey everyone, I have a question about the pricing model for Vectorize, specifically regarding metadata filtering. I structure my data by using metadata to filter vectors into different collections within a single index. For instance, one index might hold 1 million vectors organized into 1,000 collections, and every query I run is filtered by metadata to target a specific collection.

Does that mean I’m billed based only on the vector dimensions of the filtered collection, or do I incur costs based on the entire index’s dimensions regardless of the metadata filter?

Thanks for any insights!

I want to create an index with 1M vectors which will have around 10K namespaces and each query only needs one subset. If entire index's dimensions are used, we would end up with a huge bill.

I have an index with almost 1M vectors. I have also created a metadata index on one of the properties. When i query this index with a metadata filter, I am getting back results in 2-3 seconds, sometimes more. Is this kind of latency normal with Vectorize or am I doing something wrong?

lavisht22•4/2/25, 10:42 AM

I have the same vectors in postgres with pgvector and I was getting similar performance, wanted to try out vectorize to check if there are any performance gains.
