Is there a way we can support local data (pandas dataframes, polars dataframes, etc) that doesn't require a user to have volume writing permissions?

Lots of useful features require memtables, so it'd be nice if we can make this work without this flag.

Hi @cpcloud,

Not sure what you mean by "support local table", it would be to replace the volume created by a local table instead I guess.
If memtable is useful even when only reading tables (not writing or anything else).

Then a local path would lead to a local table validation/creation, without any CREATE VOLUME required.

I'll look into it!
My only concern is the support of "local commands" if the table is local, but let's see
