[MapProxy] Looking for Vector Data Proxy Server

Hello Dominic Napoleon,

Most web server software such as Apache httpd, NginX and HAproxy are
capable of proxying any http or https requests. So these can also be used
for proxying of (vector-) tiles and WFS.

Besides just proxying raster data, MapProxy has several other features,
such as caching, reprojecting and support for multiple service types (wms,
wms-c, tms, wmts, etc.) plus providing capabilities (service metadata) and
extra services like legend requests or feature info requests.

If you want similar features for vector data, such a proxy software would
be able to retrieve vector data from many different sources, cache the data
as vector tiles and would be able to reproject and stitch tiles together in
order to support several vector data retrieval formats and services (wfs,
kml?, geojson?, ).

I am not currently aware of such vector-data proxying software. If anyone
knows about a project that does for vector data and services what MapProxy
does for raster data and services, I would also very much like to learn
about that.

One solution might be NginX configured as a caching proxy for proxying
vector tiles from a remote source. Such an NginX service would only support
vector tiles. If tiles are in the cache, NginX can deliver them very
quickly. If not available, you can configure NginX to retrieve new tiles
from for instance a database or other external source. Remote sources are
mostly much slower but retrieval needs to be done only once per unique
vector data tile.

Another solution might be Geoserver. Geoserver can convert many
vector sources into vector tiles. It also supports WFS. However, I believe
Geoserver cannot currently retrieve and manage vector tiles or WFS data
from remote servers / services (=proxying) very efficiently?
