Andy Grove created ARROW-2521:
---------------------------------
Summary: [Rust] Review Array design before first release
Key: ARROW-2521
URL: https://issues.apache.org/jira/browse/ARROW-2521
Project: Apache Arrow
Issue Type: Improvement
Components: Rust
Reporter: Andy Grove
Assignee: Andy Grove
Fix For: 0.10.0
Early on, [~kszucs] and I worked on two different designs for how to represent
Arrow arrays in Rust, each with their pros and cons.
Krisztian started out with a generics approach e.g. Array<T> which was great
until we tried to implement structs, which can contain mixed types so we ended
up using enum to represent arrays, which was great until I got to the list
types ... I don't think I can implement nested lists with this approach.
I am reviewing this again now that I am more familiar with Arrow and also my
Rust skills have improved greatly since I started working on all of this.
I will be prototyping in a separate repo, and will update this Jira once I have
something concrete to share, but I feel it is important to address this before
the first official release of the Rust version. Also, if we are going to
consider a refactor like this, it is better to do it now while the codebase is
tiny.
