Probably we should remove id from all objects. The id is used to distinguish the objects from different user and it also enable user to change the name arbitrarily. However, our user prefer the readable rather than the flexible on objects APIs.

We can address the Restful APIs guideline (shared by @eechih) if we remove the id.

For example, the following API handle the both creation and update.

POST/PUT /v0/xxx

{
   "name": "xxx"
}

It creates a object if object doesn't exist (index by name). Otherwise, it updates the object.

The above change reduces the our complex behavior of routes. However, the flexible of changing name is limited by how we use the name. For example, the Topic's name is restricted by kafka.

這個 name 應該不能使用特殊符號像是問號, 會影響到 url 的正確性

yep. this is another limit to name.

[jackyoh]

那 name 會有長度的限制嗎？

那 name 會有長度的限制嗎？

In order to avoid chaos of limit, I prefer to set up our limit of name. For instance, char + number and length limit.

Probably we should remove id from all objects.

Does this mean all objects that list in description? or any object used in our route api?

BTW, I think the version label is used when an issue link to a PR? so should we remove the version in this issue?

all objects!!!

I will remove the version label if this issue gets too large to be resolved in 0.5 :(

[saivirtue]

I will take over the rest tasks.

[chia7712]

The cleanup of id can break our UI so I plan to remove the id totally in 0.7.

@saivirtue @jackyoh Thanks for great contributions!!!
