Does the processing became slower when the edge_data table became bigger?
: Re: [postgis-users] creating topology data is slow
We are working quite big datasets (about 1 billion points and 20 million lines)
that we convert from simple feature to topology. I ran a test yesterday and we
added these 20 million lines in about 9 hours with attached attributes. This

Hello all,
I'm creating topology data from almost all world road OSM data ( More than 77
Million ways).
Processing the data with postgis topology in one shot is so long than that I
created a hexagonal grid that let me create topological data from only one or

Even this way
