PACELC theorem
The PACELC theorem, an extension of the CAP theorem, considers the trade-offs in distributed systems when confronted with network partitions. Let’s take a look at what PACELC stands for:
- Partition tolerance (P): Partition tolerance refers to a distributed system’s ability to function and provide services even when network partitions or communication failures occur. It means the system can tolerate the loss of network connectivity between different nodes.
- Availability (A): Availability ensures that every request made to the distributed system eventually receives a response, regardless of the state of individual nodes or network partitions. The focus is on providing timely responses, even if it means sacrificing strong consistency.
- Consistency (C): Consistency entails all nodes in a distributed system agreeing on the current state of the system. Strong consistency guarantees that every read operation sees the most recent write operation. However...
