In a nutshell, a data pipeline is a distributed system. Processing latency is minimum If only you can infinitely scale your data pipeline, processing latency can be guaranteed to be minimum, but we know for sure that is not true. Testing Hell Testing and quality assurance with data pipeline is a nightmare.

The default storage engine in earlier versions was MMAPv1, which utilized memory-mapped files and document-level locking. In-Memory Storage Engine, as the name suggests, stores data in memory for faster performance and lower latencies. However, due to its reliance on the virtual memory subsystem, it is not suitable for larger datasets.

I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. There are impressive estimates for latency for 5G, but reality has a tendency to be harsh on such predictions.

It keeps application processing closer to the data to maintain higher bandwidth and lower latencies, adheres to compliance regulations that don’t yet approve cloud managed services, and allows data center capital investments to be fully amortized before moving to the cloud. More details can be found in the Dynatrace documentation.

On modern Linux systems, the difference in overhead between forking a process and creating a thread is much lesser than it used to be. These sit between the database and the clients, sometimes on a seperate server (physical or virtual) and sometimes on the same box, and create a pool that clients can connect to.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+).

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated. As well, very few cases are in need to have a full system/solution to provide scalability with sharding.
