[postgis-users] Tips for making queries fast when dealing with big data

[Shaozhong SHI]

Hello,

Has anyone got experience in making queries fast when dealing with big data?

Some times, queries get 'killed'..  Sometimes, a message of 'out of
memories' appears.

What are the best approaches for making queries fast will certainly be of
interest.

Looking forward to hearing from you.

Regards,

Shao
