List instances using Searchlight

Registered by Matt Riedemann on 2017-03-05

To support efficiently listing instances across multiple cells Nova plans to integrate support for using Searchlight. This will be an optional feature but recommended for large deployments with multiple cells since using Searchlight will be perform better than the compute API getting instances across multiple cells and then merge sorting them in Python.

This isn't going to happen for Pike per the summit discussion. The best we can do in Pike if we have time is some proof of concept discovery code and testing, but I'm going to defer this to Queens so we can focus on things that are ready for review in Pike since we're 5 weeks from feature freeze now. -- mriedem 20170622

At the Queens PTG we decided to not go this route for a variety of reasons. We're going to try to efficiently list filtered/sorted instances via the DB APIs across cells instead so I'm closing out this blueprint. -- mriedem 20170919
