Yes. For an interesting Desktop project in Java which needed to be fast. Using SQLite with the FTS extension, custom Java extension functions and also some BLOB tables with protobuf worked wonders. I also built a Google Go library wrapping the sql amalgamation file and then cross compiled it for Android and iOS but with some more SQLite extension (GIS), which the stock Android/iOS SQLite did not have. This was some time in 2017 I guess. I am a big fan of SQLite. You can integrate it in all kinds of stuff and adapt it to your needs. Compiling it is also straightforward.
