Description of Linked Ticket
Epic Summary
Summary
Implement a single queue at the data node ingress layer. This queue will be backed by a max concurrency ticketing system.
Motivation
Queuing at the data node ingress layer allows the customer to avoid data-bearing nodes receiving a number of operations that would induce overload symptoms. Backing the queue with a max concurrency ticketing system allows two levels of observability and constraint, having insight into both how many operations are currently running, and how many operations would like to begin running.
