RabbitMQ - Clustering
You want to design a RabbitMQ cluster with high availability and fast failover. Which node type combination is best?
AOne disc node with multiple RAM nodes
BAll RAM nodes only
CAll disc nodes only
DOne RAM node with multiple disc nodes
Step-by-Step Solution
Solution:

  1. Step 1: Consider durability and speed

    Disc nodes provide durability; RAM nodes provide speed and fast failover.

  2. Step 2: Combine node types for balance

    One disc node ensures state persistence; RAM nodes speed up cluster operations and failover.

  3. Final Answer:

    One disc node with multiple RAM nodes -> Option A

  4. Quick Check:

    High availability + fast failover = disc + RAM combo [OK]
Quick Trick: Mix disc for durability and RAM for speed [OK]
Common Mistakes:
MISTAKES
  • Using only RAM nodes losing durability
  • Using only disc nodes losing speed
  • Misplacing RAM node as single node
