For large volume data we should use batch to process it faster. B is the correct ans.

Here nothing is mentioned about interfacing with the legacy system. Is this legacy system emitting one or multiple events at a time? Or does a process need to pull some data from DB or file? How are you going to write a file in batch processing? In aggregator? Does file write operation support concurrency? The question doesn't provide all information and hence is confusing.

Selected Answer: B
DWH must have a daily snapshot, typically achieve through batch processing. Gathering the transactions in a (near) real-time through EDA or micro service architecture would require changing the legacy source system.

Selected Answer: B
It should be B. D does not make sense. Microservice architecture has nothing to do with CSV file with millions of record. For file with millions of record, the only approach that will work is batch triggered.
