• Offline-First Landscape – 2025

  I’m doing offline-first apps at work and want to emphasize that you’re constraining yourself a lot trying to do this. As mentioned, everything fast(ish) is using SQLite under the hood. If you don’t already know, SQLite has a limited set of types, and some funky defaults. How are you going to take this loosey-goosey typed data and store it in a backend database when you sync? What about foreign key... - Source: Hacker News / about 1 year ago

• Stop Syncing Everything

  > I'm thinking to give it a try in one of my React Native apps that face very uncertain connectivity. Some similar stuff you may want to investigate (no real opinion, just sharing since I've investigated this space a bit): - https://rxdb.info. - Source: Hacker News / over 1 year ago

• Show HN: Triplit – Open-source syncing database that runs on server and client

  Looks like it could be a more batteries-included/opinionated alternative to RxDB (https://rxdb.info). The relational queries might help some people who tend to think in SQL as opposed to documents (as in CouchDB or MongoDB) and the WebSockets for synchronization will help people get started more quickly. (RxDB provides interfaces for those who want to implement their own storage engine and/or synchronization... - Source: Hacker News / about 2 years ago

• HackNote

  Some years ago "offline-first" was a thing: https://web.archive.org/web/20170720174332/http://hood.ie/initiatives/#offline-first Primarily based on PouchDB/CouchDB. Now the site redirects to RxDB. https://rxdb.info/ There's still a site by that name but I don't quite understand what's the intention https://offlinefirst.org/. - Source: Hacker News / over 2 years ago

• Ask HN: How Can I Make My Front End React to Database Changes in Real-Time?

  I'm interested in this problem also! I think there is a large overlap with projects that market/focus on offline-first experiences. AFAIK this problem can be solved by: 1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take! - Source: Hacker News / over 2 years ago

• Materialized views are obviously useful

  Did I miss in the article where OP reveals the magic database that actually does this? 3rd party solutions like https://readyset.io/ and https://materialize.com/ exist specifically because databases don’t actually have what we all want materialized views to be. - Source: Hacker News / about 1 year ago

• The Missing Manual for Signals: State Management for Python Developers

  This triggered some associations for me. Strongest was Cells[0], a library for Common Lisp CLOS. The earliest reference I can find is 2002[1], making it over 20 years old. Second is incremental view maintenance systems like Feldera[2] or Materialize[3]. These use sophisticated theories (z-sets and differential dataflow) to apply efficient updates over sets of data, which generalizes the case of single variables.... - Source: Hacker News / about 1 year ago

• Category Theory in Programming

  It's hard to write something that is both accessible and well-motivated. The best uses of category theory is when the morphisms are far more exotic than "regular functions". E.g. It would be nice to describe a circuit of live queries (like https://materialize.com/ stuff) with proper caching, joins, etc. Figuring this out is a bit of an open problem. Haskell's standard library's Monad and stuff are watered down to... - Source: Hacker News / over 1 year ago

• Building Databases over a Weekend

  > [...] `https://materialize.com/` to solve their memory issues [...] Disclaimer: I work at Materialize Recently there have been major improvements in Materialize's memory usage as well as using disk to swap out some data. I find it pretty easy to hook up to Postgres/MySQL/Kafka instances: https://materialize.com/blog/materialize-emulator/. - Source: Hacker News / almost 2 years ago

• Building Databases over a Weekend

  I agree. So many disparate solutions. The streaming sql primitives are by themselves good enough (e.g. `tumble`, `hop` or `session` windows), but the infrastructural components are always rough in real life use cases. Crossing fingers for solutions like `https://github.com/feldera/feldera` to solve their memory issues, or `https://clickhouse.com/docs/en/materialized-view` to solve reliable streaming consumption.... - Source: Hacker News / almost 2 years ago
