210,245 users (5 per zip code) 21MB data, 17MB index
33,579,939 friend relationships (30-300 per user)1286MB data, 631MB index
1,198,639 activities (5-10 per user, 1 week period) 111MB data, 95MB index
Performance Testing
Used free zip code data to generate database
Wednesday, July 29, 2009
• Very impressed with PostGIS
• 2D or 3D indexing? 2D for now
• Partition tables by time? No
• Segment geographically? No
• Specific SQL can have a big impact
• Mix of explicit storage and dynamic calculation
Performance findings
Confident we can scale to millions of users
