NoSQL Database implemented by Python (like Redis)

Primary LanguagePython

Introduction

This is a NoSQL Database implemented in Python (running in memory like Redis).

Multiple data structures are implemented and the corresponding APIs are well developed.

Development Tool

  1. Python 3.6.0
  2. Flask

Project Goal

  1. Build 5(or more) data structures:

    • ELEMENT => The most common variable which can be Integer / String.
    • LIST => A Sequential container of flexible length.
    • HASH => A Key-Value mapping.
    • SET => A container composed of unique data.
    • ZSET => A sorted container composed of unique data.

  2. Implement CRUD operations for each data structure mentioned above.

  3. Implement DB-level operations like TTL, Lock, Authentification.

  4. Develop a client program and server program for use.
