US Patent 10169359 Distribution content-aware compression and decompression of data

Distributed content-aware compression and decompression techniques are provided for data, such as seismic data. Data is compressed by obtaining a file chunk of a plurality of file chunks of a larger file, a start offset of the file chunk, and a data descriptor indicating how the file chunk should be processed based on characteristics of the larger file. Headers in the file chunk are compressed using a substantially lossless header compression technique to obtain compressed headers. Samples in the file chunk are compressed using a substantially lossless sample compression technique to obtain compressed samples. The compressed headers and compressed samples are packed into a single bit stream comprising a compressed version of the file chunk. The compression can be performed in a physical or logical layer of storage nodes of a file system or in compute nodes of a computing cluster. The compression can be executed on demand by an external agent and/or in a background mode by a storage operating system.
