C++ implementation of ratarmount

Ratarmount++

This repository provides a prototype of ratarmount implemented with C++ to improve performance over the Python version, which has its limits in the Python layer itself and Python's global interpreter lock. For now, this module is a proof of concept and will only work with uncompressed and bzip2 compressed TAR files, which do have preexisting <file name>.sqlite.index files created by the original ratarmount.

Installation

sudo apt install g++ cmake
git clone --recursive https://github.com/mxmlnkn/ratarmountpp.git
cd ratarmountpp; mkdir build; cd build
cmake ..
make -j $( nproc )
sudo make install

Usage

Ratarmount++ requires a preexisting index file, therefore the workflow is like follows:

ratarmount mylargetar.tar mountpoint  # creates index
fusermount -u mountpoint
ratarmount++ mylargetar.tar mountpoint
src/tools/benchmark-reading mountpoint
