Webb30 okt. 2024 · Parquet uses the record shredding and assembly algorithm which is superior to the simple flattening of nested namespaces. Parquet is optimized to work with complex data in bulk and features different ways for efficient data compression and encoding types. WebbThere are 3 different formats for SequenceFiles depending on the Compression Type specified: Uncompressed format. Record compressed format. Block compressed format. The SequenceFile is the base data structure for the other types of files like MapFile, SetFile, ArrayFile, and BloomMapFile.
