How to output KML by GAE
- by Niklas R
Hi
I use KML for a google map where entities have a geopt.db
coordinate and soft memory limit was exceeded with 213.465 MB after servicing 1
requests total.
The log says /list.kml 200 13130ms 10211cpu_ms 4238api_cpu_ms
The file list.kml which outputs about 455,7 KB is a template as
follows
<?xml version="1.0" encoding="UTF-8"?><kml xmlns="http://
www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2"
xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://
www.w3.org/2005/Atom">
<Document>{% for a in list %}
<Placemark>
<name>
</name>
<description>
<![CDATA[<a href="http://{{host}}/{{a.key.id}}"> {{ a.title }} </a>
<br/>{{a.text}}]]>

<Point>
<coordinates>
{{a.geopt.lon|floatformat:2}},{{a.geopt.lat|floatformat:2}}
</coordinates>
</Point>
</Placemark>
{% endfor %}
</Document>
</kml>
Is there a memory leak in the template or the python that passes the list variable?
Can I improve using other template engine or other framework than
default?
Is kmz compression a good idea in this case?
Thanks in advance for any suggestion where or how to change the code.
