SQLite has a pluggable table API (virtual table).

I thought it was sufficient to implement a different backend, but apparently that's not the case. I hope the direction they push is to extend the vtable API to make it capable of their use case.


Does someone have results for the benchmarks comparing the different backends, they say that it brings improvements but no numbers.


This forum post has some info on benchmarking SQLite with two different backends:

https://sqlite.org/forum/forumpost/9aa5e1dcffde1336

See the "preliminary results" link.


Why the no-fork and not a branch?

Just maintain a dev branch on SQLite, the same as on, say, NGINX, and only merge into mainline after > 3 years of use by the lots of users that are safe using dev.

Will get it battle tested better and fatser, and in the hands of far more users. Why have a not-a-fork fork?


Aside, anyone used the java sqlite driver https://github.com/xerial/sqlite-jdbc in production (webapp with multiple users)? Has the driver been reliable?


Yes and yes, though I used it for a read-only application.


Yep, works well.


What library do you plan on using for the attribute based encryption?


The "not forking" graphics look a lot more like forks then spoons or knives. Let's call that forking. Or if they insist on renaming monkey patching to something new: lets name it pitchforking or tridenting.


If you're going to be pendantic about terminology: monkey patching is patching at runtime in a dynamic language like Ruby or Python.


> LumoSQL is a modification (not a fork) of the SQLite embedded data storage library

So it modifies SQLite to add various features, thus deviating from SQLite as it is while still using it as its base? That's what a fork is.


A fork implies that the projects are going diverge, which it seems they don't want to happen.

From a quick reading of that page I think the LumoSQL authors are making the effort to maintain their set of modifications as some kind of patch which will continue to be compatible with future SQLite versions as they are released.


Maybe it would be better referred to as a “tracking fork”. At least, that’s how I’d think about it.


Historically these are called patches or patchsets.


> A fork implies that the projects are going diverge,

...which is exactly what you're doing when you branch off a release branch and start applying your own commits with no plan to merge them back to mainline.

> which it seems they don't want to happen.

They are already doing it. They are only arguing that they can reapply the same patches over the next release branch, but that doesn't really change anything.


SQLite is public domain, LumoSQL is MIT-licensed.

If they want to stay as close as possible to upstream, you'd think they'd either keep it public domain, or else choose a public domain-equivalent license (such as MIT-0, 0BSD, CC0, etc).
