Thanks for digging into that Even!
Can I create my new .fgb in sections?
If I limit the number of source rows with -sql, doing that multiple
times with -update, will it still build the entire R-tree when writing
to the destination?
That would actually be a bad idea. Appending in FlatGeobuf is not a
native capability. It is emulated by storing into RAM the new features,
and then writing at dataset closing the full .fgb file from the original
one + the new features. You would actually need a lot more RAM than
doing a single ogr2ogr run.
I'm looking for a way to get the desired results.
Rent a bigger VM instance... or contribute a RAM-friendly implementation
of the RTree building :-)
