Daily Term: HDFS

HDFS

HDFS (Hadoop Distributed File System) is a distributed file system designed to store large datasets across multiple nodes with high fault tolerance. It splits files into blocks, replicates them across nodes, and ensures availability even if nodes fail. For example, HDFS might store petabytes of log data for analysis with Hadoop. HDFS excels at scalability and reliability, but it’s optimized for large, sequential reads, not random access.
