Ticket #290 (closed enhancement: fixed)
ODBC driver: significant performance improvement on selecting geometries
|Reported by:||danstoica||Owned by:||danstoica|
ODBCDR: Currently the geometries are retrieved as BLOBs ("image"), using the specialized ODBCGetData(). This approach is slow, about 2000 geometries/sec.
During the implementation of the SQLServerSpatial provider (against MS SQL Server 2008) a hybrid technique for retrieving the geometries has been developed and tested, allowing a performance boost of about 10 times. Ported this enhancement to ODBCDR.
