Velocity in big data refers to the rate at which data is generated and transferred. This is a crucial consideration for businesses that require their data to flow fast so that they may make the best business decisions possible.
A company that employs big data will have a massive and constant flow of data being created and transferred to its destination. Data could come from a variety of places, including machines, networks, smartphones, and social media. This data must be swiftly digested and analyzed, sometimes in near real time.
In healthcare, for example, several medical devices are now available to monitor patients and collect data. Collected data is needed for anything from in-hospital medical equipment to wearable devices.
