Simple Hashing vs. Consistent Hashing
Here are the key differences between simple hashing and consistent hashing:
| Aspect | Simple Hashing | Consistent Hashing |
|---|---|---|
| Load Distribution | Simple hashing often leads to uneven load distribution. | Consistent hashing ensures a more balanced load distribution. |
| Scalability | Simple hashing does not scale well with node changes. | Consistent hashing scales smoothly with additions or removals of nodes. |
| Data Redistribution | Simple hashing requires extensive data redistribution when nodes change. | Consistent hashing minimizes data movement during node changes. |
| Handling Hotspots | Simple hashing is prone to creating hotspots. | Consistent hashing effectively mitigates hotspots. |
| Overhead | Simple hashing involves high overhead during changes. | Consistent hashing reduces overhead with minimal data movement. |
| Flexibility | Simple hashing lacks flexibility in dynamic environments. | Consistent hashing adapts well to dynamic changes and failures. |
| Resource Utilization | Simple hashing may lead to inefficient resource use. | Consistent hashing optimizes resource utilization across nodes. |
| Reliability | Simple hashing can lead to node overload and failures. | Consistent hashing enhances reliability by evenly distributing load. |
| Management Complexity | Simple hashing increases complexity in data management. | Consistent hashing simplifies data management and distribution. |
How Consistent Hashing is Better in Handing Hotspots than Simple Hashing?
Consistent hashing is a technique used in distributed systems for data distribution. It ensures data is evenly spread across nodes, adapting well to changes. Simple hashing maps data directly, often causing imbalances. This imbalance can create “hotspots,” where certain nodes are overloaded. Consistent hashing reduces hotspots by distributing data more uniformly. It also minimizes data movement when nodes are added or removed. In this article, we will explore why consistent hashing is better at handling hotspots than simple hashing.
