All of the retrievers do support pre-filtering, you just add the where clause within the retriever function. We're working on more query optimization to make this automatic also.
I'm a big SQL stan here and I love the concept and if you ever wanna chat about how it might integrate with dbt let me know :)
conceptual questions:
1) why did you pick SQL?
to increase the Total Addressable Userbase with the thinking that a SQL API means more people can use it than those who know Python or Typescript?
2) What isn't or will never be supported by this relational model?
what are the constraints? Clickhouse comes to mind w/ it's intentionally imposed limitations on JOINs
3) databases are historically the stickiest products, but even today SQL dialects are sticky because of how closely tied they are to the query engine. why do you think users will adopt not only a new dialect but a new engine? Especially given that the major DWH vendors have been relentlessly competing to add AI search vector functionality into their products?
4) mindsdb comes to mind as something similar that's been in the market for a while but I don't hear it come up often. what makes you different?
playground feedback:
1) why are there no examples that:
a) use `JOIN` (that `,` is unhinged syntax imho for an implicit join)
b) don't use `*` (it's cool that there's actual numbers!)
2) i kinda get why the search results defaults to a UI, but as a SQL person I first wanted to know what columns exist. I was happy to see "raw table" was available but it took me a while to find it. might be have raw table and UI output visible at the same time with clear instructions on what columns the query requires to populate the UI
Would love to chat about it, and talk about dbt integration. There's a few use cases that have come up where this would be really helpful. I'll PM you.
1) So we do actually have a python and typescript API, it's just the console web experience is SQL only as it feels the best for that kind of experience. The most important thing though is that it's declarative. This helps keep things relatively simple despite all the configuration complexity, and is also the best for LLMs/agents as they can iterate on the syntax without doc context.
2) Yeah exactly, joins is something we can't do at the moment, and i'm not sure the exact solution their honestly. Under the hood most of Shaped's offline data is built around Clickhouse, and we do want to build a more standard SQL interface just so you can do ad-hoc, analytical queries. We're currently trying to work if we should integrate it more directly with ShapedQL or just keep it as a separate interface (e.g. a ShapedQL tab vs a Clickhouse SQL tab).
3) We didn't really want to create a new SQL dialect, or really a new database. The problem is none of the current databases are well suited for search and recommendations, where you need extremely low latency, scalable, fault-tolerance, but also the ability to query based on a user or session context. One of the big things here is that because Shaped stores the user interactions alongside the item catalog, we can encode real-time vectors based on those interactions all in an embedding query service. I don't think that's possible with any other database.
4) I haven't looked into mindsdb too much, but this is a good reminder for me to deep dive into it later today. From taking a quick pass on it, my guess is the biggest difference is that we're built specifically for real-time search, recommendations and RAG, and that means latency, and ability to integrate click-through-rate models and things becomes vital.
Thanks so much for the playground syntax, have some follow up questions but i'm going to pm you if that's okay. Agreed on the being able to see which columns exist.
Neat examples, and I agree that extending SQL like this has real potential. Another project along very similar lines is https://github.com/ryrobes/larsql
I work on https://github.com/xtdb/xtdb which is broadly Postgres-compatible with a few key SQL extensions (SQL:2011 bitemporal tables + immutability, first-class nested data, pipeline syntax, etc). Built on Arrow and the JVM but is otherwise mostly from scratch.
XTDB is perhaps not directly relevant to the topic at hand, but I am a firm believer that ML workflows can benefit from robust temporal modelling.
I had a look, so how would I bring my data into it.
By exposing my database to services somewhere else in the network. Oh and somewhere else is the US.
Fat chance in hell I can anyone in my company look at that or even think about legally applying it with some serious data. (I'm in EU. Yes, a lot of people and companies use US services. Currently it looks like NONE of these can legally do.)
It looks interesting, but it needs a on premise solution.
Fair enough. We're releasing our first bring-your-own-cloud (BYOC) offering in April. We're working with a big e-commerce platform in Germany that has data sovereignty requirements so totally get the constraint and excited to offer something like this. We're starting with AWS then will do GCP at end of year. Full on-premise will still be awhile though to be honest.
For the cloud platform though (console.shaped.ai), i'd recommend just testing with some synthetic or deanonymized data or our demos and then if you're interested in BYOC reach out after April!
RE: syntax
For casual use, I kinda always liked the whole MATCH/AGAINST syntax for old school Innodb, though obviously things have changed a lot since those days. But it felt less like calling embedded functions and more like extending SQL’s grammar.
Regarding the rest, it seems like a reasonable approach at first tinker.
Makes sense. Implementation simplicity was part of the reason we didn't go for this. Currently the language is a transpiler, which maps SELECT and FROM into the retrieval stages, WHERE as post-filter stage, ORDER BY as score stage and REORDER BY to the final stage reranker. Because the text lookup is pushed through to the retriever we put it there. In the future we'll have more logic in the language compilation process which means that we can move things around a bit and under the hood they all get pushed to where they need to anyway.
Thanks for the feedback on the privacy policy, let me see if we can get that changed. For what it's worth we don't share personal information with anyone, this is likely just overly defensive legal writing on our part.
You can think of Shaped more like a vector store + feature store + ML inference combined into one service. This bundling is what makes it so easy to get state-of-the art real-time recommendations and search performance.
E.g imagine trying to build a feed with pgvector, you need to build all of the vector encoding logic for your catalog, then you need to build user embeddings, the models to represent that and then have a service that at query time encodes user embeddings from interactions does a lookup on pgvector and returns nearest neighbor items. Then you also need to think about fine-tuning reranking models, diversity algorithms and the cold-start problem of serving new items to users. Shaped and ShapedQL bundles all of that logic into a service that does it all as one in a low-latency and fault-tolerant way.
> This replaces about 500 lines of standard Python
isn't really a selling point when an LLM can do it in a few seconds. I think you'd be better off pitching simpler infra and better performance (if that's true).
i.e. why should I use this instead of turbopuffer? The answer of "write a little less code" is not compelling.
This line comes from a specific customer we migrated from Elastic Search, they had 3k lines of query logic, and it was completely unmaintainable. When they moved to Shaped we were able to describe all of their queries into a 30 line ShapedQL file. For them the reducing lines of code basically meant reducing tech-debt and ability to continue to improve their search because they could actually understand what was happening in a declarative way.
To put it in the perspective of LLMs, LLMs perform much better when you can paste the full context in a short context window. I've personally found it just doesn't miss things as much so the number of tokens does matter even if it's less important than for a human.
For the turbopuffer comment, just btw, we're not a vector store necessarily we're more like a vector store + feature store + machine learning inference service. So we do the encoding on our side, and bundle the model fine-tuning etc...
>> Apply diversity logic so your Agent/User doesn’t see 10 nearly identical results
On Instagram this is a good thing, but here the example is hotel and flight search, where a more deterministic result is preferable.
In the retrieve → filter stage, using predicate pushdown may be more performant: first filter using hard constraints, then apply hybrid search ?
Makes sense! Agreed on the diversity for agents being a bit contrived here.

I've been loving all these projects that are integrating LLMs/encoding directly into the language. There's so much power there.
Someone shared with me these the other day and we're inspired to add more remote LLM calls directly into ShapedQL now: https://github.com/asg017/sqlite-rembed https://github.com/asg017/sqlite-lembed
Fairly easy to extend SQLite, Postgres and MariaDB/MySQL!
Curious what relational database do you @refset use? Is the code open source? Is the engine from scratch? What general dialect does it support?
Cheers!

I always assume cloud based services are a moat against the simplicity of the code bases used for these types of demos.

If I upload my own data, who exactly is it shared with? I can't find a list of subprocessors and this line in the privacy policy is alarming:

Subprocessors are here: https://docs.shaped.ai/docs/v2/support/security
Thanks for the feedback on the privacy policy, let me see if we can get that changed. For what it's worth we don't share personal information with anyone, this is likely just overly defensive legal writing on our part.
Is there a major difference between pgvector and shapedql?
You can think of Shaped more like a vector store + feature store + ML inference combined into one service. This bundling is what makes it so easy to get state-of-the art real-time recommendations and search performance.

this is not my area of expertise, but doesn't that still assume the LLM will get it done right?
Shorter code is easier to understand and maintain, for both man and machine
This idea that it no longer matters because Ai can spam out code is a concerning trend.
Great potential! Love the idea
