Load balancing web service by rejecting connections
Granted: October 26, 2021
Patent Number:
11159406
A load balancer allocates requests to a pool of web servers configured to have low queue capacities. If the queue capacity of a web server is reached, the web server responds to an additional request with a rejection notification to the load balancer, which enables the load balancer to quickly send the rejected request to another web server. Each web server self-monitors its rejection rate. If the rejection rate exceeds a threshold, the number of processes concurrently running on the web…

Granted: October 26, 2021
Patent Number:
11157493
Embodiments are disclosed for fast data fetching and rendering. In some embodiments, in response to receiving a page display request, a system constructs a static, possibly nested query for retrieving all the data to be rendered for the page and stores the query result in a data store. For a future page display request, the system similarly constructs a query and determines whether the query can be resolved from the data store. If not, the system constructs a “diff query” to fetch…
