Expand runtime_field data types to include ranges

[sypste]

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.

I believe this issue is best suited here in the elasticsearch repo. If you disagree I will gladly return it to kibana.

Thanks for submitting this enhancement suggestion. It is something we would like to develop, but it is not on our immediate roadmap, because of prioritization and taking into account the limited usage of range data types compared with other data types. We will get to it at some point. If a community member is interested, we would welcome a contribution for this feature.

Hi @javanna, I have figured out that I have to create an entry for Range Field in getRuntimeFields() in IndicesModule and create the script class corresponding to it. Can I start working on it?

@javanna please take a look at it
