Authorization and Access Control In RabbitMQ, authorization dictates the operations a user may execute on given virtual hosts. Virtual Hosts and Resource Permissions In RabbitMQ, virtual hosts craft distinct isolated environments that upgrade security and resource segregation by restricting inter-vhost communication.

As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). But I'm not completely sure.

While hardware such as intelligent SANs, Solid State Disk, and other advancements have helped speed things up, wasted space in index can translate to wasted space in the buffer pool as well as wasting more I/O. There are exceptions to every rule or best practice. With modern hardware, the cost estimation of 5 is outdated.

A data pipeline is a software which runs on hardware. The software is error-prone and hardware failures are inevitable. In certain scenarios exactly-once semantics is possible but the best you can do is at-least-once or at-most-once. A data pipeline can process data in a different order than they were received.
