US Patent 10063632 Low-latency high-throughput scalable data caching

Low-latency high-throughput scalable data caching is disclosed. For example, a data source is connected over a network to a load balancer server with data cache. A load balancer service and a data cache service execute on processors on the first load balancer server to receive, by the load balancer service, a request from a client device over the network. The load balancer service requests a data entry associated with the request from the first data cache service. The data cache service retrieves the first data entry from the first data cache, which stores a first plurality of data entries that is a subset of a second plurality of data entries stored in the data source. The load balancer service modifies the request with the data entry. The load balancer service sends a modified request to a plurality of receivers.
