[gdal-dev] RFC 31 - OGR 64bit Support

[geographika]

Hi,

As I understand it the only reason to use 64bit integers for IDs would 
be for tables with more than 2 billion records (in the positive range).
There is a related question on StackOverflow about this 
http://stackoverflow.com/questions/2124631/sql-server-int-or-bigint-database-table-ids
Are there really feature classes with this many records in existence?
Regards,

Seth
