Kafka - Multi-Datacenter and Replication

Given this MirrorMaker 2 config snippet:

{
  "source.cluster.bootstrap.servers": "source:9092",
  "target.cluster.bootstrap.servers": "target:9092",
  "topics": "topicA,topicB",
  "num.streams": 3
}

How many parallel streams will MirrorMaker 2 use to copy data?

A3

B2

C1

D4

Step-by-Step Solution

Solution:

Step 1: Locate num.streams setting
The config sets "num.streams" to 3, which controls how many parallel streams MirrorMaker 2 uses.
Step 2: Understand effect of num.streams
More streams mean more parallelism in copying data, so MirrorMaker 2 will use 3 streams here.
Final Answer:
3 -> Option A
Quick Check:
num.streams = 3 [OK]

Quick Trick: Check num.streams value for parallelism count [OK]

Common Mistakes:

Assuming default 1 stream if not read carefully
Confusing topics count with streams count
Ignoring num.streams config
