Batch and Stream Processing

Question 1

What are the three classes of system?

Answer 1

1. Services (Online System)
2. Batch Processing Systems (Offline Systems)
3. Stream Processing Systems (near-real-time systems)

Question 2

Answer 2

A service waits for a request and handles it as quickly as possible and sends back a response. The primary performance metrics are response time and availability

Question 3

What is a Batch Processing System?

A batch processing system takes a large amount of input data, runs a job to process it, and produces some output data. Jobs can take from minutes to days. Batch jobs are often scheduled to run periodically. The primary performance measure of a batch job is usually throughput.
