Jorge Leitão commented on ARROW-10128: -------------------------------------- I am sorry, this is a non-issue. I looked at it more carefully and I mis-interpreted our implementation. > [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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
