Ross data compression

  • What is the LZRW compression algorithm?

    Lempel–Ziv Ross Williams (LZRW) refers to variants of the LZ77 lossless data compression algorithms with an emphasis on improving compression speed through the use of hash tables and other techniques.
    This family was explored by Ross Williams, who published a series of algorithms beginning with LZRW1 in 1991..

  • Common examples are executable programs, text documents, and source code.
    Some image file formats, like PNG or GIF, use only lossless compression, while others like TIFF and MNG may use either lossless or lossy methods.
  • Lempel-Ziv-Oberhumer (or LZO) is a lossless algorithm that compresses data to ensure high decompression speed.
    It has the following characteristics: Data compression is similar to other popular compression techniques, such as gzip and bzip.
    It enables very fast decompression.

Does SAS support binary data compression?

BINARY to use the RDC (Ross Data Compression) algorithm, which is highly effective for compressing medium to large (several hundred bytes or larger) blocks of binary data. (The SPD Engine does not support binary compression.) all tables that are created during a SAS session.

How do i compress a data file?

To compress a data file, you can specify one of the following:

  1. COMPRESS=CHAR to use the RLE (Run Length Encoding) compression algorithm COMPRESS=BINARY to use the RDC (Ross Data Compression) algorithm indicating the percentage of reduction that is obtained by compressing the file
,

What happens if a data set is compressed?

There is also significant decrease in memory due to data set compression.
The option COMPRESS=BINARY uses the Ross Data Compression (RDC) algorithm, which combines run-length encoding and sliding window compression.

What does compress mean in SAS?

COMPRESS= system option to compress all data files that are created during a SAS session COMPRESS= option in the LIBNAME statement to compress all data files for a particular SAS library COMPRESS= data set option to compress an individual data file

COMPRESS=CHAR to use the RLE (Run Length Encoding) compression algorithm
