[dev] [jira] [Created] (LIBCLOUD-113) Node object should have an 'image'
attribute
Node object should have an 'image' attribute
--------------------------------------------
Key: LIBCLOUD-113
URL: https://issues.apache.org/jira/browse/LIBCLOUD-113
Project: Libcloud
Issue Type: Improvement
Components: Compute
Reporter: Tomaz Muraus
Priority: Minor
Node object should have an 'image' attribute which references the corresponding NodeImage object.
- need to check if majority of the APIs return info which is needed to do this in list_nodes call.
- need to evaluate the performance impact (in the best case without caching this means 1 extra request for each list_nodes call).

--------------------------------------
Perhaps a property to make the request lazily?

Tomaz Muraus commented on LIBCLOUD-113:
---------------------------------------
This would actually make the average case worse :)
If we would implement it using "lazy property" it would result in an extra request every time you access it on a different node object. If we did it in list_nodes it would only result in a single extra request (retrieve all the nodes, retrieve all the images, set image property on all the retrieved nodes).
We could solve this problem using per-object cache, but not sure if we want to do that.
