Note there are different internal implementations within
|
||
|
|
<literal>libmysql</literal> and <literal>mysqlnd</literal> for handling
|
||
|
|
columns of type <literal>MYSQL_TYPE_GEOMETRY</literal>. Generally speaking,
|
||
|
|
<literal>mysqlnd</literal> will allocate significantly less memory. For
|
||
|
|
example, if there is a <literal>POINT</literal>
|
||
|
|
column in a result set, <literal>libmysql</literal> may pre-allocate up
|
||
|
|
to 4GB of RAM although less than 50 bytes are
|
||
|
|
needed for holding a <literal>POINT</literal> column in memory. Memory
|
||
|
|
allocation is much lower, less than 50 bytes, if
|
||
|
|
using <literal>mysqlnd</literal>.
