Hacker News Hacker NewsIf you find yourself wanting things like an easy way to then introspect your SQLite database, figure out what is happening in the workflow, compose individual tasks, make workflows trivially callable, etc, give Temporal a look.
Alongside this, I have mostly moved away from files for agents. Markdown and JSON are great, but also feel like traps when building out smaller local apps. LLMs are great at SQLite and you can render anything you want out of it (Markdown, JSON, etc). It saves a lot of tokens when an agent can just query a specific row instead of having to fire up jq or grep through markdown. You get a nice portable self contained data management system that encourages agents to be more disciplined about how they structure their data than a bunch of files. It also continues to scale into MySQL/Postgres if your little local projects start to outgrow or become more formal, you already have schema and discipline around data.
This is a foundational principle of computer science. It seems to me that the "SQLite for everything" crowd is a little bit inexperienced.
Personally, lots of ETL can just be taken care of locally without involving enterprise databases. In such cases, DuckDB is 5x-10x better than SQLite and orders of magnitude simpler/faster than spinning up a dedicated Postgres database.
For general scripting, there's no match between a 20-lines awk script and a much cleaner, robust, maintainable equivalent SQL script based on DuckDB.
I just hope MotherDuck don't need to pump/dump for IPO - it would be sad losing that tool for the usual corporate greed.
I've been testing different storage engines for my agent harness and I can get up to 7.5k concurrent sessions on a single vCPU with SQLite whereas Postgres crashes or runs out connections.

Another fascinating fact: our countries TLD has been stolen Ocean's 11 style (I am not kidding). After Czechoslovakia split into Czech Republic and Slovak Republic, the newly created Slovak .sk TLD has been under the care of people from the local university. The university also had some offices that they were leasing out. Someone had leased this office space (EDIT: this is important as this means they had the same physical address), created a company that had the same name as the NGO that was taking care of the domain, so e.g. the NGO was named "My Company o.z." and the perpetrator created a "My Company s.r.o." (our countries version of the american Ltd). This person then wrote to ICANN to change the address to the "My Company s.r.o." presumably under the pretense that this was just an administrative error and from this point, they have functionally taken custody of the TLD. I was not able to find how they did it technically, but I presume they persuaded ICANN to then point to their servers instead of the real ones. After this happened, it seems that no one noticed for some time. When they noticed, they tried taking it back, but they weren't able to. For some inexplicable reason, the government during that time (Šuster era, early 2000s) gave the new company a contract that was functionally uncancellable from the government side. Later governments made this even more uncancellable and in 2017, then Minister of IT (and as of this day president!) Pellegrini made the contract literally uncancellable. As a result of this, we have one of the most expensive domains around (18e/year, rising each year for no good reason). (EDIT:) The company running our countries TLD is now a foreign entity that the whole thing has been sold to (multiple owners over time) and we as a country have no control over if I understand it correctly.
I might have gotten some details wrong as I am writing this from my memory of researching it a couple of years back, but you get the idea, crazy stuff. Here is an article in Czech [0] that tells the story a bit better, but you have to translate it.

// EDIT: I have found that the article actually links the movement to return the TLD back [1]. It also has a story tab [2], so they have something much more precise than the paraphrasing I wrote.
Funny how people are independently converging on similar patterns of "what works" here. Still feels like we're in the wild west with all these ad-hoc patterns of agent orchestration that people are coming up with.
Obligatory list of workflow engines and libraries because it's such a common need that a lot have rolled their own. [1]

Small, well defined, data model with known query patterns? Bespoke model
There probably is a place for sqlite and my project space so far hasn't yet well-aligned with it.
Building durable workflows on Postgres
In short: SQLite is not all you need, unless you’re just experimenting don’t actually care about durability, in which case you also need litestream + object storage.
Right.
