SCDB

Solid Core Database System

Solid Core Database is a basic key-value database engine that is true to the fundamentals, fast, and easy to access.

Features

• scdb is a lightweight and fast key-value storage engine that stands out for its simplicity and speed. It's modeled after the Bitcask storage architecture, renowned for its efficiency in write operations.

• The core design principle behind scdb (and Bitcask) is influenced by log-structured filesystems. In this approach, all changes are appended to the end of a log, making writes exceptionally fast because they're sequential. This design is not only quick but also ensures the integrity of your data: even in the event of a system crash, you can recover the data easily thanks to this append-only method.

• Additionally, scdb incorporates a process known as log file merging. Over time, as your application writes more data, the number of log files will naturally increase. Log file merging is a technique that combines these files to prevent fragmentation and maintain performance. It's like housekeeping for your data, ensuring that your storage remains organized and efficient.

• So, if you're developing an application that requires speedy data writes and a simple yet robust storage solution, scdb might just be the engine you're looking for. It's built to give developers like you a hassle-free experience with the storage and retrieval of key-value pairs.

SDK versions

Scdb version	Recommended Go SDK version
1.0.0-alpha	1.0.0-alpha
1.0.0	1.0.0-rc

Install Scdb Go SDK

(We plan to create an SDK repository for SCDB in the future.)

1. Use go get to install the latest version of the Scdb Client and dependencies:

   go get -u github.com/sjy-dv/scdb/scdb/pkg/scdbclient/[email protected]

2. Include the Scdb in your application:

   package main
   
    import (
        "context"
        "log"
   
        scdbclient "github.com/sjy-dv/scdb/scdb/pkg/scdbclient/v1"
    )
   
    func main() {
        conn, err := scdbclient.NewScdbConn("127.0.0.1:50051")
        if err != nil {
    	    log.Fatal(err)
        }
        defer conn.Close()
        err = conn.Ping(context.Background())
        if err != nil {
    	    log.Fatal(err)
        }
    	err = conn.Save(context.Background(), "greeting", []byte("helloworld"))
    	if err != nil {
        	log.Fatal(err)
        }
        val, err := conn.Get(context.Background(), "greeting")
        if err != nil {
    	    log.Fatal(err)
        }
        log.Println(string(val))
        err = conn.Del(context.Background(), "greeting")
        if err != nil {
    	    log.Fatal(err)
        }
    }
