Duckdb Wasm limitation

Question

I don't know how to check or increase the memory limitation of duckdb wasm. I'm using chrome and I import some parquet into the browser, one of them has 234Mb of data

I did my research and the limit seems to be 256Mb by default, but i don't know how to increase it.

Yes, i read it , but it seems to me that the limitation on my computer is far from 1Gb , that is why I thought there was a way to increase it to Gb. — Antho

"browsers may impose even stricter limits" is also important to note. — robertklep

Current limitation as of today is 4GB and comes from WASM itself :

https://duckdb.org/docs/stable/clients/wasm/overview.html

You can check your memory limit doing following query :

SELECT current_setting('memory_limit');

Please take also in consideration following warning from duckdb which explains why the actual memory consumption can be higher than the specified memory limit.
