Due to the error, it seems your issue is either an old Poolboy version (try updating it) or an old Erlang version. It seems tone the former. ## _José Valimwww.plataformatec.com.br...

I don't know how Rustler works, but if we were writing C code, we should be using [`enif_make_resource_binary`](https://www.erlang.org/doc/man/erl_nif.html#enif_make_resource_binary). The idea is that we would create a resource in Rust (I...

Yes, I understand. My point is that, instead of creating a large binary and slicing it, you should slice the original Arrow binary/resource, without creating a new large binary. I...

So using enif_make_resource_binary is not practical because we don't have a single large binary. We could point to each individual buffer as a resource, but that is blocked by #452,...

@joshuataylor I have just learned that Polars uses its own reference counting system. This means that we could directly point to the underlying Polars/Arrow binaries by using make_resource_binary, then bumping...

@cigrainger so last time we talked we were not sure if we should allow the mask in `filter_with` (instead of `filter`) or introduce the `mask` function. Between those options, any...

Once we land the macro version of `filter/2`, there is little to no reason to use `filter_with/2`? So yeah, it makes sense to have `mask/2` then!

I also think it may be easier to go with Postgrex/Myxql directly rather than Ecto. I have a hunch that if we use Ecto we will be mostly fighting against...

As an example, I think Ecto queries do not allow the field names to be strings. So at least this would need to change. Plus Ecto brings changesets, schemas, transactions,...
