When should I use partitioning instead of sharding?

Partitioning is best when you want to divide a large dataset into smaller, manageable pieces within a single database. Sharding, on the other hand, is ideal for distributing data across multiple databases to improve performance and scalability.

Can you give me an example of when to use each?

Sure! Use partitioning for a large customer database where you want to separate data by region. Use sharding for a social media platform where user data needs to be distributed across multiple servers for load balancing.

What are the performance implications of each?

Partitioning can improve query performance by reducing the amount of data scanned. Sharding enhances performance by distributing the load, but it can introduce complexity in data management and consistency.

Are there any downsides to using sharding?

Yes, sharding can complicate your architecture, making it harder to manage transactions and maintain data consistency across shards.
