What do you think about improving cache replacement clock-sweep algorithm in
PostgreSQL with adaptive version proposed in this article:
Are there some well known drawbacks of this approach or it will be interesting
to adopt this algorithm to PostgreSQL and measure it impact om performance
under different workloads?
I find this ten years old thread:
but it mostly discus possible patent issues with another algorithm ARC (CAR is
inspired by ARC, but it is different algorithm).
As far as I know there are several problems with current clock-sweep algorithm
in PostgreSQL, especially for very large caches.
May be CAR can address some of them?
