global activity history
collecting everyone's activity history
this is a really big proposal, are you sure?
we're talking maybe 35-40 TB of raw data, if you want data from all time,
or consuming many hundreds of PGCRs per second, ongoing, forever, if you just want to keep up with current activity
the tl;dr here is, PGCRs are incrementing one at a time. you can request
https://stats.bungie.net/Platform/Destiny2/Stats/PostGameCarnageReport/1/
then
https://stats.bungie.net/Platform/Destiny2/Stats/PostGameCarnageReport/2/
then
https://stats.bungie.net/Platform/Destiny2/Stats/PostGameCarnageReport/3/
etc.
if you really wanted to. but do you want to? that's up to you.
if you do this, expect to deal with large gaps in the data, missing instance IDs, times when it seems like they have just stopped being generated, etc.
