<p>Hi,</p>
<p>Connection pooling is an internal implementation driver of each
driver. You have to be careful about multi-threaded use cases if
you want to implement that though. The PostGISRaster driver has
some connection pooling. See PostGISRasterDriver::GetConnection()</p>

<p class="MsoNormal"><span style="font-size:11.0pt">A Python
program can invoke GDAL driver through gdal.open() to
read/write raster/vector data. Is it possible for the GDAL
driver to be reused in order to avoid reinitializing the
driver for each gdal.open() call? For example, if a GDAL
driver to a database implements a connection pool, will each
gdal.open() call be able to ask the driver to retrieve a db
connection from the connection pool, instead of creating a
new database connection?
