A checksum is a fixed-length string from a cryptographic hash that verifies data integrity in distributed systems. It helps detect corruption during data transfer, ensuring clients receive error-free data or can request a clean copy.
Explore the core components of a Distributed File System (DFS) — replication, scalability, and consistency — and how they contribute to the reliability, performance, and integrity of distributed storage solutions.
Understand the internal architecture of a distributed file system (DFS), including key components like metadata servers, data nodes, replication mechanisms, and a real-world example using Hadoop HDFS.
Learn what a Distributed File System is, how it works, its key features, examples like HDFS and GFS, and common use cases such as cloud storage and big data processing.
A Clustered Index controls the physical order of data in a table, making range queries and sorting extremely fast. It organizes rows on disk by the index key and is usually the primary key, with only one clustered index allowed per table.
