Yes, the results look more reasonable now. I see x3 differrence in QPS with pipeline mode and this probably correct - we have not optimized pipelining and Redis/Valkey have recently...
can you please try running the master with `--compression_mode=0` and see if it helps?
how many CPUS there are on master and replica. Can you provide the htop output of the master during that time?
@jojoxhsieh how do you monitor QPS and latency from the memtier output?
Did you run replica on a differrent VM from master? Did you run memtier on a differrent VM as well? Overall you should use 3 nodes
if you run on the same VM your CPU threads are contended by master/replica/memtier. Dragonfly does not like to share its CPU time. you can run master/replica processes on the...
I run on 3 VMs with 16 cpus each. These are the graphs that memtier recorded. You can see some latency increase as well as latency spikes for SETs but...
@vyavdoshenko it should not happen. Another transaction should not be able to delete the key that is being changed by rename as we lock these keys for mutations. I suggest...
Can you provide (simulate) the possible order of operations that causes such bug?
Lets put it on hold for now and handle other issues.
