Liu Jiayu commented on THRIFT-5587:
-----------------------------------
I agree with that:
* for binary use the 16 bytes and byte ordering defined in RFC
* for Thrift JSON use the dashed canonical form, no huge use cases for other
types, since users may just choose to use string instead
** one caveat is whether to ignore casing (in the RFC it is case insensitive)
I'm not sure why 3 is a concern if a library / language does not have built-in
support for UUID. But I think the general rule is to default to use stdlib if
present, but each language can add a param to tell the generator to generate
library dependent code if it is appropriate and needed.
A brief survey of uuid support:
* Java has JDK support
[https://docs.oracle.com/javase/7/docs/api/java/util/UUID.html] since 1.5 (we
are currently at Java 8)
** Kotlin follows that
* Rust defers to a library [https://docs.rs/uuid/latest/uuid/index.html]
although it used to be part of the library
* Python3 has built in support [https://docs.python.org/3/library/uuid.html]
* JS (node) has multiple UUID libraries, e.g.
[https://www.npmjs.com/package/uuid]
> Introduce uuid as additional builtin type

> Key: THRIFT-5587
> URL: https://issues.apache.org/jira/browse/THRIFT-5587
> Project: Thrift
> Issue Type: New Feature
> Components: Compiler (General)
> Reporter: Jens Geyer
> Assignee: Jens Geyer
> Priority: Major
>
> I hereby propose to add *{{uuid}}* as an additional built-in basic type.
> *Rationale:*
> * Uuids (or Guids) are a state of the art and well-understood way to
> identitify data entities.
> * There is support in next to all languages' runtimes to generate, convert
> and store such data.
> * Although conversion to and from string or binary is certainly possible, it
> is also rather cumbersome.
> * A distinct datatype enables us to sent it in the most suitable way across
> the wire: JSON=text, Compact=binary
> *Remarks*
> * -I am open to discuss the term "guid" vs "uuid". Coming from NET platforms
> I would tend to guid, but I am open to uuid (or even both) as well. That's
> just a detail.-
> * If no significant concern is raised, I would move on and implement C#,
> Delphi and Haxe bindings (as sub-tasks) myself and leave the rest to the
> community.
