bpftrace is a new open source tracer for Linux for analyzing production performance problems and troubleshooting software. For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. software Kernel software-based events.

In 2018, a widespread adaptation of Kubernetes for big data processing is anitcipated. Over last few years, we have seen several attempts to run data workload in the containers especially distributed big data frameworks like Apache Hadoop, Apache Storm [3] , and Apache Spark [4] [5] without any software modifications.

Finally, not inlining resources has an added latency cost because the file needs to be requested. Luckily, multiple companies have been working on open-source QUIC and HTTP/3 implementations for over five years now, so we have several mature and stable options to choose from.
