[0041] The following are the overall steps of the present invention, as follows:
[0042] like Image 6 As shown, the present invention proposes an adaptive compression method of a distributed file system, comprising:
[0043] Step 1, setting the compressed file format to form a compressed data stream, the compressed data stream is composed of header information and a plurality of data blocks, wherein the header information is used to determine whether the compressed data stream has been compressed;
[0044] Step 2, receiving the file to be compressed, compressing the file to be compressed according to the compressed file format to generate the compressed data stream;
[0045] Step 3, setting an index file, wherein the index file is composed of multiple records, each record maintains data information of the data in the compressed data stream, and the index file is used to quickly locate the compressed data stream.
[0046] The data information includes the location of the fi...
