Hi, all:

Today, the DB behind patchwork.kernel.org was in a semi-permanent state 
of suffering due to someone trying to suck down all patches in the 
linux-arm-kernel project. This is what the API request looked like:

GET 
/api/1.1/patches/?project=62&before=2019-11-01T00:00:00&per_page=100&page=6150 

The query behind this takes about 1 minute to run on a 20-core HT Xeon 
system and requires creating a huge temporary file (there are 18375 
patches in that project).

So, two questions, really:

1. Any indexes we can put in place to make this query perform better?
2. Is there a way to disable anonymous API access?

-K
