what is the size limit of duckdb in wasm?

[kesavkolla]

Is there any restriction on the size of the database in wasm?

[carlopi]

Currently memory is constrained by WebAssembly 32 bit pointers, so short of 2GB.

There is a potential solution to this in the mid-term, but nothing that is currently worked on.

I thought WebAssembly added support for up to 4GB two years ago. Is it not an option to explicitly opt in to using more memory?

Can the size of the database only be 2 GB, or does duckdb WASM only have 2GB of memory to run queries? Is there an actual limit to the size of a parquet file you analyze in duckdb wasm?

@carlopi So currently all duckdb wasm usage is all about reading remote data via parquet/csv/json files. There is nothing that can be saved on client side is that correct?

It seems wasm supports 64bit now in a few browsers? What needs to be done to utilize this with duckdb for larger databases client side.
