We have continuous integration on the performance benchmark. When a regression occurs, we can download flame-graphs to investigate the problem. However, it's not intuitive to compare two flamegraphs a…

While benchmarking Restate, I noticed that we spend a lot of time in `rocksd::DBImpl::WriteImpl` when trying to commit the `PartitionStoreTransaction` from the different partition processors. I suspec…
