Rules
-----
Segments are loaded and dropped from the cluster based on a set of rules. Rules indicate how segments should be assigned to different historical node tiers and how many replicants of a segment should exist in each tier. Rules may also indicate when segments should be dropped entirely from the cluster. The coordinator loads a set of rules from the database. Rules may be specific to a certain datasource and/or a default set of rules can be configured. Rules are read in order and hence the ordering of rules is important. The coordinator will cycle through all available segments and match each segment with the first rule that applies. Each segment may only match a single rule

No. If the Druid coordinator is not started up, no new segments will be loaded in the cluster and outdated segments will not be dropped. However, the coordinator node can be started up at any time, and after a configurable delay, will start running coordinator tasks.
This also means that if you have a working cluster and all of your coordinators die, the cluster will continue to function, it just won’t experience any changes to its data topology.
