Abstract
System and method for implementing a reliable persistent random access compressed data stream is described. In one embodiment, the system comprises a computer-implemented journaled file system that includes a first file for storing a series of independently compressed blocks of a data stream; a second file for storing a series of indexes corresponding to the compressed blocks, wherein each one of the indexes comprises a byte offset into the first file of the corresponding compressed block; and a third file for storing a chunk of data from the data stream before it is compressed and written to the first file. The system further comprises a writer module for writing uncompressed data to the third file and writing indexes to the second file and a compressor module for compressing a chunk of data from the third file and writing it to the end of the first file.
