can someone clarify what return type here should be? https://github.com/Eventual-Inc/Daft/blob/4e4012c95c26ffdba8c1d18e6a86c9bb52966b94/src/daft-core/src/array/ops/list.rs#L476-L479 https://github.com/Eventual-Inc/Daft/issues/2862

Hmm let me take a look. One second.

look at the issue I linked

So looks like each element is a JSON list. On first impressions, seems like

DaftResult<ListArray>

seems like the proper answer. @Kevin Wang does that sound right?

I know @Sammy Sidhu mentioned a Map type

It looks like it should be a list of structs, so the return type should be

DaftResult<ListArray>

. You can also return a

DaftResult<Series>

. The list array gets converted into a series eventually anyway

@jay and I spoke about this and we think it makes sense to return a

MapArray

where the Key is the type that is inside the

ListArray

and the Value is the

Count

.

going to want to pair program w/ someone to finish this so far have https://github.com/Eventual-Inc/Daft/blob/b52b2822f8996fe9c6010f5f283251de08d8842d/src/daft-core/src/array/ops/list.rs#L478-L549

Finishing up some docs right now, but maybe in an hr?
