partiql-lang-kotlin VS tresql

Ion is heavily used on the retail side of Amazon, but it's only recently started to appear in AWS products.

AWS is starting support PartiQL (https://partiql.org/) queries in some places and PartiQL uses Ion's type system internally.

Yep, that's exactly the vision here. One of the biggest sources of precedent and inspiration for us here is https://partiql.org/ which is picking up a fair bit of traction across AWS. Also see https://rockset.com/

QLDB allows you to create a ledger that acts similar to a schema or table space in a traditional database. Once you've created this ledger, you create a table through the SQL-like query language PartiQL that also enables you to interact with the data.

PartiQL[0] is an open source library that is a superset of SQL that I really like. It supports querying nested structures inside columns, so if a column contains some JSON data you can use the standard dot notation to query nested JSON data directly

PartiQL was introduced to AWS DynamoDB, with AWS making the announcement in 2020 making the life of developers easier, with the comfort of executing commands similar to SQL.

I haven't tried it, but I'm pretty sure the problem is that timestamp (and it's various capitalizations) is a keyword in PartiQL (https://github.com/partiql/partiql-lang-kotlin/blob/master/lang/src/org/partiql/lang/syntax/LexerConstants.kt#L221). To get it to be interpreted as an attribute name, you need to enclose TimeStamp in double quotes.

I'm really excited about languages that build on or are compiled to SQL, in the long-term (because I think it will take a very long time to build adoption).

The ones that particularly excite me are shorthands for SQL, even though their heavy use of symbols may be a detriment. One particular use case is in easily defining authorization policies.

I am not very excited by datalog/prolog-based languages because I think logic languages are too unnatural to ever go mainstream. But I'd be excited to be wrong or for logic languages to become more friendly.

Here are some others I'm watching.

Are there any policy-language-libraries-backed-by-sql like Polar but that aren't based on logic programming languages? I don't really want to learn logic programming for this purpose nor do I want to require it on my coworkers.

I guess I'm just looking for a SQL shorthand that can easily interpolate request variables and session variables but that gets declared in code where a route is declared. Just spitballing but something like `(blogs.id = $req.blogid).userid = $session.userid OR (users.id = $session.userid).isAdmin`.

This [0] is close but it doesn't have enough momentum to be usable in every language you'd want.
