What is the difference between partitioning and sharding in databases?

Partitioning is the process of dividing a database into smaller, more manageable pieces, while sharding is a specific type of partitioning that distributes data across multiple servers.

Can you explain how sharding works in more detail?

Sure! Sharding involves splitting data into smaller chunks called shards, which are stored on different database servers. This helps improve performance and scalability.

Are there any downsides to using sharding?

Yes, sharding can introduce complexity in data management and may require additional effort for data consistency and query optimization.

When should I consider using partitioning or sharding?

Consider partitioning for large datasets that need to be managed efficiently, and sharding when you need to scale out across multiple servers for performance.
