Kafka - Advanced Stream Processing

Why do advanced Kafka patterns often use stateful processing instead of stateless in complex flows?

AStateless processing automatically handles retries and ordering

BStateful processing tracks context and history needed for complex decisions

CStateful processing requires no storage and is simpler

DStateless processing is faster and preferred for complex flows

Step-by-Step Solution

Solution:

Step 1: Define stateful vs stateless processing
Stateful keeps track of past events or context; stateless does not.
Step 2: Understand why complex flows need state
Complex flows require remembering history or aggregations to make correct decisions.
Final Answer:
Stateful processing tracks context and history needed for complex decisions -> Option B
Quick Check:
Complex flows = need for stateful processing [OK]

Quick Trick: Stateful = remembers past, needed for complex logic [OK]
