Conditions and Breakouts

[claytongentry]

Differentiates the concept of a condition from a breakout. Metrics schemas provide fields for each condition on its own, as well as the intersection of all conditions across all groups (though never within a given group).

Conditions provide the simple definitions used to group events. For example, us might mean the event's context.geo.country = 'US'. Breakouts describe groups of conditions that are mutually exclusive. For example, if an event is us then it is necessarily not global, or mobile and necessarily not tablet.

Breakouts can be intersected to produce mobileUs or tabletGlobal but never usGlobal.
