We are currently trying to switch the backend for our Geoserver from Postgis to MongoDB. Apart from our Geoserver-Heatmap Transformations it is working quite well.
While visualizing the Heatmap Geoserver seems to ignore the BBox constrains, this results in a full table scan even when zooming in.
Normally a filtering with $geoIntersec is done on the defined BBox, but not while using
the Heatmap Transformation.
Anybody with similar problem and possibly a solution?
We are using Geoserver Version 2.15.2. Here the Geoserver logs with the logged MongoDB query.
