MatrixKV

1 Introduction

MatrixKV is a key-value storage database optimized for Rocksdb based on NVM(AEP).

MatrixKV uses PMDK as read and write interface using NVM, and PMDK must be installed.

> make -j64

Only Makefile is currently supported, and cmake is not implemented.

If you want to use MatrixKV, you need to modify the configuration, in include/rocksdb/option.h.

std::shared_ptr<NvmSetup> nvm_setup = nullptr;

To learn more about NvmSetup, you can view the file include/rocksdb/nvm_option.h.

Run db_bench can refer to the test script file test_sh/matrixkv_test_4value.sh , you can :

> ./tesh_sh/matrixkv_test_4value.sh
> nohup ./tesh_sh/matrixkv_test_4value.sh >out.out 2>&1 &     ##Run in the background

We implement MatrixKV based on the Rocksdb v5.18.3 version code. If you want to view the rocksdb code:

> git checkout 641fae60f63619ed5d0c9d9e4c4ea5a0ffa3e253

If you want to see what parts of the code have been modified:

> git reset --mixed 641fae60f63619ed5d0c9d9e4c4ea5a0ffa3e253

It is recommended to use vscode to view.
