An epic story about looking for a Redis substitute and not finding anything even similar.

Testing and test program versions

The *_m.cpp programs are the testing program versions which output the statistics in CSV-ready format. This means you should directly append the output of the files to a .csv file and it should work.

The file has the following columns: n_threads, n_insertions, n_reads, block_size, size_t, memory_consumption, total_requests, time_elapsed, requests_per_second

The decimal numbers have the American format (dot).

What is this?

This is just an exercise to get to know some DBs and object storage systems, and practice a bit of Bash, make and cmake, compiling and linking, and LaTeX. In the end, it's a comparison between several Redis competitors to see which one could work best to be used as a cache for a distributed file system (LustreFS).
