Right but that is an artificially created demo by the author to justify the solution being presented (no offense). The question is how common are ~GB large SQLite databases in the real world relative to databases that are ~MB large?

In my experience SQLite databases of millions of rows of raw tabular data tend to compress very well into dozens of megabytes. Indeed SQLite is often touted as a file format for applications.

I'm running magnetico (https://github.com/boramalper/magnetico) on my VPS. I currently have an index of 1.6M magnet links stored in a 5GB database.

SQLite is most interesting not when the database is small, but when there are very few writes and all you do is reading. You can also look at https://datasette.io/ and see how SQLite is perfect for representing a lot of datasets and querying them

Even if you compress it, you need it in client memory which can also be a dealbreaker. Some people might need it for some projects, I know I did.

    Most workstations have GBs of available memory. If not you can dump it in indexeddb as a raw data store.

    I never disputed that it would be useful for some use cases. I only said it would be unusable with high latency links. If you have a low latency link and aren’t running very complex queries with lots of random seeks, then this should work fine for you.

My team has a few TB of data in SQLite files that are themselves dozens of GB each.

We're using them as a replacement for leveldb's sstables, but with the structure of full SQL. It is highly effective.

  • Do you think your team’s usage of SQLite is representative of the average SQLite user?

    • This is the fundamental flaw of 80% thinking. The fact that SQLite continues to reach for more users is what has made it such a successful general-purpose tool.

    • Where has it been suggested that this is the best solution for "the average SQLite user", instead of a tool you can use if it fits your requirements? To take your 10MB number, the article starts by mentioning you can probably just download the entire thing if you aren't above that exact same number.
