We’re excited to announce that we are adding support for vector storage and search into MySQL and PlanetScale. Soon, you’ll be able to use PlanetScale as a vector database for all of your AI needs without needing to adopt a second tool. You can sign up to be notified of release at planetscale.com/ai. What are vectors? A vector is a one-dimensional array of real number values: [1, 1] is a vector, as is [1.5, 8.889, 9.234]. Each element represents an attribute or a dimension, and the position of that element in the array represents a “point.” In three-dimensional space, a vector of [2, 3, 5] would have 2 as the x-coordinate, 3 as the y-coordinate and 5 as the z-coordinate. In real-world applications of artificial intelligence, vectors are in significantly higher dimensionality — well above 1,000! Modern databases are already very good at storing lists of numbers. Storing vectors as a raw datatype is not interesting, like points on a globe or …
