JSON serialization is crucial in Python for seamless data interchange between dataclasses and JSON objects. By converting dataclass instances to JSON strings using asdict(), developers ensure compatibility with external systems, web services, and file storage. This process, facilitated by the json mod...

Partition Tolerance - The system continues to operate despite arbitrary partitioning due to network failuresNetworks aren't reliable, so you'll need to support partition tolerance. You'll need to make a software tradeoff between consistency and availability.CP...
