Latest Patents
Mark Callaghan holds a patent for a "Tiered Data Storage Architecture." This invention focuses on storing data in different tiers of a database based on the access pattern of the data. Immutable data, which does not change or changes infrequently, is stored in a first storage tier, while mutable data, which changes more often, is stored in a second, more performant storage tier. The second tier offers higher write endurance and lower write latency compared to the first tier. Writes are performed at the second storage tier, while reads can occur on both tiers. The synchronization of the storage tiers is managed through a trigger, such as a specified schedule, ensuring that data is efficiently managed.
