ODBC driver: significant performance improvement on selecting geometries

Reported by: danstoica Owned by: danstoica
Priority: major Milestone: 3.3.1
Component: ODBC Provider Version: 3.2.0
Severity: 3 Keywords:
Cc: External ID: 1041996

Description

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.
