Examples and Case Studies
- Google’s MapReduce: MapReduce is a distributed data processing framework used by Google and other organizations for large-scale data processing tasks. It relies on a global state to coordinate the execution of parallel map and reduce tasks across distributed nodes, ensuring data consistency and fault tolerance.
- Apache Kafka: Kafka is a distributed streaming platform that processes and delivers real-time data streams. Kafka maintains a global state of message offsets across distributed partitions, ensuring message ordering and fault tolerance for stream processing applications.
- Amazon DynamoDB: DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). It utilizes a distributed global state to manage data replication, consistency, and fault tolerance across multiple data centers, ensuring high availability and durability for applications requiring low-latency data access.
- Apache ZooKeeper: ZooKeeper is a distributed coordination service used for maintaining configuration information, naming, and synchronization in distributed systems. It employs a global state to maintain a hierarchical namespace and coordinate distributed operations such as leader election and distributed locking.
- Facebook’s TAO: TAO is a distributed data store developed by Facebook for storing and serving social graph data. TAO maintains a global state of user relationships and interactions across distributed data centers, enabling efficient and scalable access to social graph data for Facebook’s services.
What is the Global State of a Distributed System?
Global State of a Distributed System, we dive into how computers team up across the internet. Think of it like a giant puzzle where each computer holds a piece. The global state is like a snapshot of the whole puzzle at one time. Understanding this helps us keep track of what’s happening in the digital world, like when you’re playing games online or chatting with friends.
