行排序的C++库

This is a set of row-reordering algorithms and data compression compression schemes implemented in C++. The goal of these algorithms is to maximize the compression ratio of database tables through row reordering. Is this for you? This library is strictly for researchers with a working knowledge of C++ that are interested in studying our implementation. For a simple demo (in Java) of the Vortex order described in the paper, please see https://github.com/lemire/SimpleVortex Requirements LZO2 library: http://www.oberhumer.com/opensource/lzo/ Readily available on Linux. Available on macos through fink (for example). Usage We expect CSV input files (comma-separated values). make tods2011 ./tods2011 myfile.csv
