Thanks Jonathan,

That’s good to know.

Correct.  They will be ordered closest-first.

Unfortunately it's not possible for the near or medium future to do 
farthest-first.  HNSW index gets to log(n) time by only keeping a subset of the 
closest neighbors for each vector.  So you'd need a separate index with a 
inverse-cosine similarity metric, and it's not possible today to use a custom 
metric function.

(This has been GA for over a year in Elastic and Solr and so far nobody has 
needed farthest-first badly enough to add this as an option to the underlying 
Lucene library.)

You can get the distances back today, like this:

SELECT my_text, similarity_cosine(my_embedding, ?)
FROM my_table
ORDER BY my_embedding ANN OF ? LIMIT 2

Then just pass the query vector into both bind variables.

Hi,

I’ve got a question and a request about this CEP

In the example:

I presume that limit n will return the nth nearest neighbours?

If that’s the case what order will they be in? Is it posssible to reverse the 
order ?

Secondly would it be possible to return the calculated distances?  This might 
be particular important if there are n returned neighbours?

Andy,

Good to see you on the ML again! CEP-30 is slated for release with 5.0 later in 
the year. Until then, you'll need to do a local build or try it out in a 
preview in Astra. A few of us have been talking about creating a preview docker 
image since there is some interest in having it run in k8ssandra. In any case, 
this is very alpha code and should be treated as such. Reporting errors or 
unusual results would be greatly appreciated!

Re: [VOTE] CEP-30 ANN Vector Search

[Andrew Cobley (Staff)]

Hi,

I’ve got a question and a request about this CEP

In the example:


SELECT * FROM test.foo WHERE j ANN OF [3.4, 7.8, 9.1] limit 1;

I presume that limit n will return the nth nearest neighbours?

If that’s the case what order will they be in? Is it posssible to reverse the 
order ?

Secondly would it be possible to return the calculated distances?  This might 
be particular important if there are n returned neighbours?

Thanks to Benjamin for pointing out to me that committer votes count as
binding for CEPs.

That makes the updated tally 15 binding and 4 non-binding.
