In which directory are rules stored by default?
Rules are stored in the metadata store. You can also search the user/dev groups for more information about rules.
It seems they are stored in druid_rules in case anyone else is interested.
There’s a config that you can use to name your rule table. The default is druid_rules. For more info about this particular version, you can look at: http://druid.io/docs/0.6.146/
