Latest Patents

Fletcher's latest patents include a "Data store indexing engine with automated refresh." This invention discloses systems and methods to implement an indexing engine that maintains an index in an index store for a storage object in a data store. The index store may be implemented using an in-memory storage cluster separate from the data store. The storage object can have multiple indexes, each with different filtering or sorting criteria for the data. Updates to the storage object are received as an update stream by the indexing engine, which applies the updates based on configurable indexing rules. To service a query, a query engine retrieves a set of keys from the index store and then fetches the corresponding data from the data store or another index.

Another significant patent is "Indexing partitions using distributed bloom filters." This invention describes methods, systems, and computer-readable media for indexing partitions using distributed Bloom filters. The data indexing system generates multiple indices for various partitions in a distributed object store, with each Bloom filter corresponding to one or more fields of an individual partition. This allows the data indexing system to efficiently determine which partitions may contain a specific value, optimizing the data retrieval process.
