描述
Describe the feature:
runtime_fields currently don't support range, e.g. date ranges, as data types (docs). This could be useful for analytical use cases that rely on durations.
Describe a specific use case for the feature:
An index may hold two or more fields that mark the start and end of a period, e.g. a session. There is currently no easy way to visualize such date ranges within Kibana using runtime_fields for experimental purposes, instead an index mapping would have to be deployed grabbing data from said date fields.
