I have 2 indices: first, static with custom geometries (geo_shape) and second is time-based stream of logs with coordinates (geo_point).
I need to show the custom geometries from the 1st index in a color palette that represents how many documents of the second index fall inside.
I was hoping for some native functionality would be available, but I can only see "Term Joins" dialog, when adding a layer to a map. Howver I cannot join by attribute. The only existing relation between the 2 indices i a spatial relation.
Is there any workaround on how to do such visualization in Kibana?
Otherwise I guess I have to implement some custom Logstash filter in order to match by an attribute. Or maybe it could be achieved with a lookup filter.
