What is a .sequencefile file?

SequenceFile is a flat file format prevalent in Hadoop environments, designed to store sequences of binary key/value pairs. It's a core component of the Hadoop ecosystem, optimized for efficient storage and retrieval of large datasets. The format is block-compressed, which significantly reduces storage space and improves I/O performance. SequenceFiles are particularly useful for storing intermediate data generated during MapReduce jobs, as well as for archiving large volumes of data. They support different compression codecs, including Gzip and Snappy, allowing users to balance compression ratio and processing speed. The key and value pairs can be of any data type, making SequenceFile a versatile format for various data processing tasks. The format also includes metadata, such as the compression codec used and the class names of the key and value types, enabling efficient deserialization and processing. SequenceFiles are often used as input and output formats for Hadoop jobs, providing a robust and scalable solution for managing large-scale data.
