What is the difference between database sharding and replication?
Database sharding involves splitting a database into smaller, more manageable pieces called shards, while replication involves copying data from one database to another to ensure redundancy and availability.
Can you explain the benefits of sharding?
Sharding improves performance by distributing the load across multiple servers, enhances scalability, and allows for better resource utilization.
What are the advantages of replication?
Replication provides data redundancy, increases data availability, and can improve read performance by allowing read operations to be distributed across multiple replicas.
When should I use sharding over replication?
Use sharding when you need to scale out your database horizontally due to high traffic, while replication is ideal for improving data availability and fault tolerance.
