RocksDB-server

RocksDB-server is a remote call wrapper for RocksDB. It provides an interface to the client program for remote operation of the database. I'm considering adding the cluster support.

Motivation

This project is derived from the little-work assigned by PingCAP.

Demo

Build & Run

Supported platform: Linux.

Make sure you have libuv and rocksdb installed.

Just clone the repo and execute make command.

# run the server
./run-server [database_dir] [tcp_port]

# run the test program
./run-client [Database_IP] [Database_PORT]

Client interface

// construct a handler
DBserver db("127.0.0.1", 8888);

// connection
db.Connect();

// PUT
db.Put(key, value);

// GET
db.Get(key, &value);

// DELETE
db.Delete(key);

// SCAN
db.Scan(key1, key2, pairs);

Architecture

The client performs command parsing and network message packet encapsulation. The server uses a event loop to check pending request events and put those workers into a thread pool. Because RocksDB supports multi-threading, parallel acceleration can be maximized when multiple clients perform read operations.
