Right now, to be perfectly honest, it doesn't yet. This is by design: the purely integrations-oriented side is a crowded space, and I'm not ready to jump in there yet. Stay tuned :) The focus instead has been in a place where it&#

Good question! I've spent some time looking at Calcite and similar systems. My hope is that it isn't an "either-or" but an "and". I also believe that Calcite is primarily database-oriented, as are most similar

FWIW, I've genuinely spent time trying to use it, and I've never managed to run any non-trivial query on it without having it time out. SPARQL is very expressive, but its implementations seem impossible to optimize and as a resu

Thanks for the detailed feedback, I appreciate it! I plan on writing more about all the topics you mentioned, and add docs for writing adapters and queries. I was planning on doing a "Show HN" when more of that was in place, but I

The syntax is reminiscent to GraphQL, but semantically it's a lot more expressive and not compatible. It's much closer to SQL in expressive power, actually: left joins, recursion, arbitrary filters, aggregation, etc. -- none of th

No, it isn't: it's neither about websites nor GraphQL. The query language is substantially more powerful than GraphQL, much closer to SQL. And the idea is unifying and querying any kind of data, not just websites but also databa

Trustfall author here, pleasantly surprised to find this posted! The goal of Trustfall is to be the LLVM of data sources. GraphQL, OpenAPI, JSON (with JSON schema or not), SQL, RDF/SPARQL -- and none of them can natively talk to each o

For an alternative, GraphQL-like take on a related problem ("efficiently query any combination of data sources, from APIs to DBs to raw files"), check out the Trustfall language mentioned in the sibling comment: https:/&#x2F

Try it with a query that has 40 joins with multiple joins to the same table from different places, and let me know if you still think it's easy :) At work I've seen SQL queries that are thousands of lines long that would make that

SQL really sucks. In general I'm not a fan of SQL-like syntax since it makes queries with lots of joins really difficult to read -- it's hard to keep track which value came from where. GraphQL has some neat ideas and I really love

This repo is great! Always nice to see an end-to-end compiler example for a real programming language. Unfortunately, real programming languages are very complex, so writing compilers often gets bogged down in complexity, edge cases, and &q

(Post author here.) Agreed with the parent comment. To restate the same thing in another way in the hope of avoiding confusion: It isn't a bug in the compiler if the compiler is non-deterministic in the presence of UB. Such behavior do

Fortunately, this post includes a link to an excellent 45min talk on undefined behavior which does go into a fair bit of the detail you were looking for. I encourage you to click it -- it's right in the post's introduction. The pu

That's why I said "falls under the hat of" :) I promise the talk is relevant. `-fwrapv` is an attempt toward doing such a thing for signed integer overflow specifically. I bet it's a pain to maintain because it significa

When you say "searches" are you referring to regular web search (e.g. Google) or something more specialized? Just wondering if there's a good way to programmatically search "old" records like these.
