[RFE] API to fetch list of hosts without full host details
Last modified: 2018-10-31 07:22:03 EDT
Description of problem: A couple of users have expressed interest in a "host list only" API. This would be useful when scripting and looping over lots of hosts. If it took the same params as the existing /hosts api but returned only the host ID and hostname, that would be ideal. There are a performance issues with the existing /hosts API call that are being addressed[1]; however even if it was lightning fast, a more minimal result set is still useful for scripting. This is similar to Spacewalk's listActiveSystems call[2] which does not return system details. The RFE came about from users with spacewalk scripts that run much slower after porting to Katello. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1445623 [2] http://www.spacewalkproject.org/documentation/api/2.3/handlers/SystemHandler.html#listActiveSystems
The listActiveSystems call takes approximately 2 sec for 2K hosts. This new API would need similar performance, at least under 10 seconds for 5K hosts.
