Discuss what is consistent hashing ?
- One of the data distribution techniques in a distributed system is known as consistent hashing.
- This is done to ensure that a minuscule adjustment within the system does not result in an entirely re-mapping of keys to nodes.
- In cases such as distributed caching and sharding, consistent hashing is vital in ensuring the uniform distribution of data.
Top Most Asked System Design Interview Questions
System Design is defined as a process of creating an architecture for different components, interfaces, and modules of the system and providing corresponding data helpful in implementing such elements in systems.
