Answer:
The query pending_proxy_capacity is used to check the remaining capacity of a proxy server that is yet to be fulfilled. It provides information about the resources that are currently allocated to other processes but are not actively being used, thus indicating how much capacity is available for new requests. This can be useful in load balancing scenarios or when managing the allocation of resources for different tasks.
For example, let’s consider a scenario where a proxy server has a total capacity of 100 requests. At a given moment, 70 requests are actively being processed, but there are 10 requests that are waiting in the queue, yet to be served. In this case, the pending_proxy_capacity would be 20 because there are 20 available slots in the server that can be utilized for new requests.
Implementing this query can help in monitoring the workload of a proxy server and make informed decisions about managing the allocation of resources. It can be particularly crucial in scenarios where the server’s capacity is limited, and efficient utilization of resources is essential.
