Druid Namespace Updates

We’ve been using namespaces heavily but something we haven’t quite figured out is how to add new ones using downtime free deploys. It seems we need to update the configuration file and restart Druid but is there a way to do this without any downtime?

Hey Dan,

In general, you can do a downtime free rolling update of Druid using the procedure documented here: http://druid.io/docs/latest/operations/rolling-updates.html

For lookups in particular, the new lookup framework in Druid 0.9.1.1 supports dynamic addition of lookups without restarting the Druid processes. Check out the release notes here: https://github.com/druid-io/druid/releases/druid-0.9.1.1
