--------------------------------
Resolution: Invalid
> [Rust] Dictionary-encoding is out of spec
> -----------------------------------------
>
> Key: ARROW-10128
> URL: https://issues.apache.org/jira/browse/ARROW-10128
> Project: Apache Arrow
> Issue Type: Task
> Components: Rust
> Reporter: Jorge Leitão
> Priority: Major
>
> According to [the
> spec|https://arrow.apache.org/docs/format/Columnar.html#physical-memory-layout],
> every array can be dictionary-encoded, on which its values are encoded by a
> unique set of values.
> However, none of our arrays support this encoding and the physical memory
> layout of this encoding is not being fulfilled.
> We have a DictionaryArray, but, AFAIK, it does not respect the physical
> memory layout set out by the spec.
