Latest Patents

One of her latest patents is titled "Distributed consistent grid of in-memory database caches." This invention involves a plurality of mid-tier databases that form a single, consistent cache grid for data sourced from one or more backend data systems. The mid-tier databases may include standard relational databases. Cache agents at each mid-tier database are responsible for swapping in data from the backend database as needed. Consistency in the cache grid is maintained through ownership locks. Cache agents also prevent database operations that would modify cached data in a mid-tier database until ownership of the cached data can be acquired. Cache groups define which backend data may be cached and the general structure for caching that data. Metadata for cache groups is shared to ensure uniformity in data caching throughout the grid. Ownership of cached data is tracked through a mapping of cached instances to specific mid-tier databases.
