[jira] [Commented] (ARROW-13449) [Format][FlightRPC] Clarify that schemas are IPC-encapsulated

["Kun Liu (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-13449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17584153#comment-17584153 ] 

Kun Liu commented on ARROW-13449:
---------------------------------

hi [~lidavidm] , it's flexible but not very clear using the bytes to represent the schema.

For example, some user meet the issue, the arrow-rs implementation the `SchameResult` with raw flatbuffer.

Details in the issue:

[https://github.com/apache/arrow-rs/issues/2445]

[https://github.com/apache/arrow/issues/13853]

 

By the way, the version of `flight.proto` in arrow-rs is out of date, I will file a pr to update the `flight.proto` in the rust version.

> FlightRPC.proto is ambiguous about whether schemas are meant to be the raw Flatbuffer or IPC-encapsulated, but all implementations choose the latter and it was intended to be encapsulated. We should update the comments.
