To clarify on what we are trying to solve for and get the definition of a distributed scheduler straight . So A Distributed Scheduler refers to a system that can handle job scheduling and execution in a scalable and fault-tolerant manner by distributing the workload across multiple servers or nodes.
we will make some assumptions with the design , as follows:
we will assume 10,000 QPS for job submissions and should be able query for jobs status .
Job execution should have minimal latency"
