purging

[Václav Bílek]

Hello

I have got a question about purging architecture. In our aplication we
use several backends and each of them serving the same data and purging
parts of it. The purging is done in a way that tends to create duplicate
purge request.
question:
1) How does purging work with duplicate request?
2) is it a problem for performance to have thousands of purges?
3) how does purge request change state from "total active purges" to
"old purges deleted" or to "duplicate purges removed"?
