It’s important to note that recommended throughput levels may vary depending on factors such as operating system type, network bandwidth availability, and hardware quality. Memory RSS (Resident Set Size) is the number of bytes that the operating system has allocated to Redis. it signifies memory fragmentation.

Without data backup mechanisms, there can be data loss or system downtime. Even worse, entire operating systems can crash, also resulting in data loss. An incremental backup, which is faster and requires less storage than a full backup, captures changes made since the previous backup. This helps minimize downtime.

On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM. Traditionally one of the major costs when moving data in and out of memory (be it to persistent media or over the network) is serialisation. What about security?
