I would like to show a marker map based on latitude and longitudes. The map is slow when there’s ~1000 pairs of lat/long mapped. Is this expected behaviour? What is the load limit to mapping lat/longs without it being slow?

Sorry, just to clarify, is any other data being returned in your query even if it isn’t displayed in the visualization?
I’d like to reopen this discussion. I have a query that is returning 3200 rows. The rows consist of latitude, longitude, and a QR code value (3 columns).
Currently Redash just freezes when trying to map all the markers…eventually have to just close the tab.

> 1000 data points is really pushing the limits of your browser performance. Redash doesn’t dynamically load points as you scroll the map. So all that data is being pushed around by your browser in real-time.
In my experience, < 500 points is the sweet spot. If you need high-performance geo visualizations then Redash isn’t the correct tool for the job.
