Study Notes
- Data consistency in distributed systems is more complex due to lack of shared memory and global clock.
- Network timeouts in distributed systems require highly fault-tolerant solutions.
- CAP theorem states that network services cannot simultaneously achieve consistency, availability, and partition tolerance.
- Databases can be categorized into CA, CP, and AP based on their ability to achieve consistency, availability, and partition tolerance.
- CA databases are single-node clusters with limited partition tolerance.
- CP databases prioritize consistency and partition tolerance over performance.
- AP databases prioritize availability and partition tolerance over data consistency.
- CAP theorem presents a trade-off between consistency, availability, and partition tolerance.
- Distributed systems require careful consideration of data consistency and system availability.
- Distributed systems can be challenging to design and maintain due to their complex nature.
