I'm the developer of the Wasm driver mentioned in the article: <a href="https://github.com/ncruces/go-sqlite3">https://github.com/ncruces/go-sqlite3</a><p>The v0.20.x series (I just released v0.20.1) should improve this <i>significantly</i>.<p>The driver was reserving lots of <i>address space</i> (with a protected, private, anonymous mapping) which doesn't play well with VMs and OSes that don't like to overcommit. It now reserves much less address space by default, and this can be reduced further.<p>I also brought SQLite WAL mode support to 32-bit archs, to Windows and (through a build tag) to any OS that with an atomic mkdir (used for locking).<p>Happy to discuss here, if you're looking for more in depth commentary.
