The magic of injecting network latency is based on netem, which is a kernel module. You can run `grep '^CONFIG_NET_\(SCH_\|CLS\)' /boot/config-$(uname -r)` to see if your machine has this module...
I fixed it in #710.
Okay, no problem, I will try to figure out the cause of this problem, and we will continue to discuss it later. In fact, in the course of my study,...
I have read the heavykeeper paper and am implementing a heavykeeper structure that does not use min-heap. The basic idea for dragonfly to introduce hotspot awareness is to set one...
@romange The Linux OS and Version is this： uname-a -> Linux VM-9-54-centos 5.4.119-1-tlinux4-0008 #1 SMP Fri Nov 26 11:17:45 CST 2021 x86_64 x86_64 x86_64 GNU/Linux
One interesting thing, from the perf results, **the performance bottleneck of HeavyKeeper-DF is focused on _find_ operation**, because ankerl::unordered_dense::map is efficient in find(string) operation, I replaced std::unordered_map in LRUCache with...
Okay, I will fix the code style issue next week. **lruCache**： As far as I understand, the original paper has very little description of the heavykeeper implementation without min-heap (Optimization...
I actually think it's a great idea, but really it's two different directions. 1. dynamically maintaining LRU/topK allows us to know the topk information in real time, so we can...
I think I can do some research in the next few weeks to see what the current interfaces are for hotspots from the major public cloud vendors.
