Microsoft patents system to alert users when new data matches their saved search
Microsoft describes a tool that checks if new data added to a database matches a user's previous search request. It uses a compact data structure called a predicate set, which includes a mask and a filter, to quickly decide if a notification is needed without checking every piece of data.
In the filing’s own words
In various examples, an event-augmented generation tool determines whether to notify a client that an ingress event modifies data associated with a query. For example, a query footprint represents data stored in a data storage system that satisfies a query. In such examples, the event-augmented generation tool generates a predicate set that represents at least a portion of the query footprint. In an embodiment, the predicate set includes a mask representing a set of values and a Bloom filter. In one example, ingress events are evaluated based on the predicate set to determine whether data corresponding to the ingress event satisfies the query.
What exactly they claim (claim 1)
1. A method comprising: obtaining data corresponding to an ingress event associated with a data store; and determining the data modifies a query footprint associated with a query by at least: generating a hash value based on the data; applying a bitmask to the hash value based on a mask included in a predicate set associated with the query; querying a Bloom filter included in the predicate set; and transmitting to a client associated with the query an indication that the ingress operation modifies the query footprint.
