Question

what does velocity in big data mean

Answer 1

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.
