Events pagination¶
Include the URL of your launchpad blueprint:
https://blueprints.launchpad.net/heat/+spec/events-pagination
This adds support to the events index call for limit, marker, sort_keys and sort_dir query parameters, allowing users of the API to retrieve a subset of events.
Problem description¶
It is now highly probable that an event-list call could end up attempting to return hundreds of events(especially for AutoScalingGroup resources). At a certain point Heat starts responding with a 500 error because the response is too large.
Proposed change¶
We should support event pagination with limit and marker query parameters. And we should also support event sorting with sort_keys and sort_dir query parameters. It will make the use of more convenient for event-list.
limit: the number of events to list
marker: the ID of the last item in the previous page
sort_keys: an array of fields used to sort the list, ‘event_time’ or ‘resource_status’, default by ‘event_time’
sort_dir: the direction of the sort, ‘asc’ or ‘desc’, default is ‘desc’
