WASM support?

[jelder]

Is it possible to connect to DuckLake from DuckDB wasm? My understanding is that the catalog is accessed using the underlying database's wire protocol, but wasm cannot yet create raw socket connections and can only use HTTP(S).

With that in mind, any plans to support catalog operations via some RESTful API?

+1 on making it possible to use the DuckDB WASM app https://github.com/duckdb/duckdb-wasm as the compute part of the DucklLake system to dynamically scale up and down "the serverless way"
e.g. via running it in Wasmtime (seems currently not intended/possible? duckdb/duckdb-wasm#1119 (comment))
simply starting one for every user (query) would be pretty fast and cheap and scale down if not needed any-more is easily possible...

"official" description from @Mytherin how it works, and what would be perfect to be done in wasm apps:

all processing happens in the client. The Postgres database serves only as the catalog server (i.e. it hands out which files need to be read for a given query). Blob storage serves only as the file system/storage layer. The reading and processing of files happens on whichever client you are using to connect to DuckLake.
