Hi HN, I built pglite-oxide: a Rust crate for running ElectricSQL’s PGlite WASI Postgres runtime through Wasmtime.

0.3.0 makes the default path much more practical: prebuilt PGDATA template, Wasmtime module caching, direct embedded API, and local Postgres URI support for SQLx/tokio-postgres.

The main use cases I care about are Tauri/native apps with local Postgres, Postgres-backed tests without Docker, and local AI apps that want app data + embeddings on device.

It can also install PGlite/Postgres extension archives; I’m especially interested in pgvector for local semantic search/RAG. The runtime assets include things like pg_dump.wasm too, so I want this to become a useful embedded Postgres toolbox rather than just a query API.

Curious what people would try to build with this.

There is also https://github.com/dapr/workflows which uses Azure Logic Apps engine on https://github.com/dapr/

I have been exploring workflow orchestration for sometime now - specifically Temporal. Temporal's authors don't recommend it for very high throughput (per workflow) use cases, although I haven't benchmarked it myself. Also using it in a SaaS environment, I would prefer some serverless deployment strategy which possibly allows scaling down to zero.

I have my eyes on flink stateful functions http://statefun.io/ The abstractions are quite low level as compared to Temporal but the overall ability to write tasks/activities as serverless functions which have access to state is quite attractive.

Would be happy to talk to someone who has explored this further.
