[jira] [Created] (ARROW-10128) [Rust] Dictionary-encoding is out of
spec
Jorge created ARROW-10128:
-----------------------------
Summary: [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
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.
