A stakeholder asks why the team needs a dedicated 'hot-warm' architecture instead of one uniform cluster. How do you explain the cost-performance trade-off?
-
A
Hot-warm architecture splits the cluster into two separate Elasticsearch clusters with no communication
-
B
Recent data on fast SSD nodes (hot) handles high-throughput indexing and search, while older data moves to cheaper HDD nodes (warm), reducing storage costs without sacrificing query speed on fresh data
-
C
Hot nodes handle writes only; warm nodes handle reads only, regardless of data age
-
D
Hot-warm requires a separate license tier and is not available in open-source Elasticsearch
