Streaming fast moving placemarks.

[irvingwa]

Hello everyone I am trying to figure out for the best course of action to stream geojson to the map. I have about 100k placemarks with images and labels that gets updated (add/remove/update) around a rate of like 500 a second or so. Is there a preferred way of doing this so the changes are done efficiently? I have been polling my datasource at a rate of every 5 seconds or so and getting the data and converting the geojson my self using the Cesium Entity API (which is consuming a lot of memory) and then I ran into this project and wanted to ask if anyone had any advice on how to best achieve this. Thank You.

dynamic pbf vector tiles from postgis database would be one option (pg_tileserv or koopjs or any dynamic pbf vector tile package)
https://docs.terria.io/guide/connecting-to-data/catalog-type-details/mvt/
otherwise use GeoServer with POSTGIS and output WMS
https://docs.terria.io/guide/connecting-to-data/catalog-type-details/wms/
or as tiles WMTS or TMS (via geowebcache) URL
https://docs.terria.io/guide/connecting-to-data/catalog-type-details/url-template-imagery/

We have about 20 million points of interest from USGS/NGA GNIS/GeoNames Data shown in Terriajs as vector tiles
and have OSM Points of Interest data as vector tiles

You can deliver vector tiles from GeoServer as well via a Community Extension

Thank you for the response would you recommend something similar with items that are "floating" with elevation?
