Primary-Replica Architecture vs Sharding
Developers should learn this architecture when building systems requiring high read throughput, data redundancy, or disaster recovery, such as e-commerce platforms, content delivery networks, or financial applications meets developers should learn sharding when building applications that require handling massive datasets or high transaction rates, such as social media platforms, e-commerce sites, or real-time analytics systems. Here's our take.
Primary-Replica Architecture
Developers should learn this architecture when building systems requiring high read throughput, data redundancy, or disaster recovery, such as e-commerce platforms, content delivery networks, or financial applications
Primary-Replica Architecture
Nice PickDevelopers should learn this architecture when building systems requiring high read throughput, data redundancy, or disaster recovery, such as e-commerce platforms, content delivery networks, or financial applications
Pros
- +It is essential for scenarios where minimizing downtime and ensuring data availability are critical, as replicas can take over if the primary fails, and read-heavy workloads can be offloaded to replicas to reduce primary node load
- +Related to: database-replication, high-availability
Cons
- -Specific tradeoffs depend on your use case
Sharding
Developers should learn sharding when building applications that require handling massive datasets or high transaction rates, such as social media platforms, e-commerce sites, or real-time analytics systems
Pros
- +It's essential for achieving horizontal scalability in databases like MongoDB, MySQL, or PostgreSQL, as it allows systems to grow by adding more servers rather than upgrading a single one
- +Related to: distributed-systems, database-scaling
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Primary-Replica Architecture if: You want it is essential for scenarios where minimizing downtime and ensuring data availability are critical, as replicas can take over if the primary fails, and read-heavy workloads can be offloaded to replicas to reduce primary node load and can live with specific tradeoffs depend on your use case.
Use Sharding if: You prioritize it's essential for achieving horizontal scalability in databases like mongodb, mysql, or postgresql, as it allows systems to grow by adding more servers rather than upgrading a single one over what Primary-Replica Architecture offers.
