[mapserver-dev] Proposal/request to implement FlatGeobuf as built-in format

[Even Rouault]

Jeff,

as a data point, perhaps you could enhance your bench with shapefiles 
through OGR ? It would be interesting to have a sense of the OGR 
overhead (that will be the same for any OGR supported datasource) to 
have an idea if it is really worth the effort to have a native 
FlatGeobuf provider for MapServer w.r.t going through OGR (it is hard to 
beat shapefile, and the current difference between shapefile and 
flatgeobuf is small)
