Default to docvalues?

We have a really tiny node (memory-wise) that runs our Marvel instance. We keep about a week's worth of Marvel data. Occasionally if people do enough aggregations across enough days then we hit fielddata circuit breakers and have to manually clear the caches.

Any chance we could have an option or just change the default of the template to use docvalues? I'm not sure we can do that by just adjusting the "settings" section and don't know that I want to change the mappings ourselves.


There's no enable doc values switch, you need to edit the mapping per field.

We are working on releasing a new version of Marvel with KB4, so we'll move to doc values then as well.
