Separating Key and Values in SSD- Conscious Storage is a paper published in 14th USENIX Conference on File and Storage Technologies in Feb 2016. I have implemented this on top LevelDB to understands the performance improvements.

The idea is to separate the key from values to minimize the I/O amplification.


I have created a program called which uses LevelDB architecture to save Key and Value Offset. The actual value is saved in a logfile inside wisckey_test_dir which get created at run time.
