There are several ways to find out this information with the easiest way being by referring to the documentation. Instead, readers should refer to the HammerDB documentation. By default, HammerDB is designed to take advantage of database system caching mechanisms such as buffer caches, query caches, or statement caches.

An example of a specification is the correct operation of the hardware of a microprocessor. An SDC is the worst possible outcome of a fault, as it can have an arbitrary impact on the correctness of software running on the hardware.

Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. If a primary server fails, a backup server can take over and continue to serve requests.

More importantly, if this works out well, this could lead to a radical improvement in performance by leveraging hardware trends such as GPUs and TPUs.
