simple-redis-server

In this project I have tried to implement a simple persisent in-memory cache. Simple-redis-server consists of a LRU cache which persisted periodcally on the disk using Write-Ahead-Log technique. Currently the cache size is 3 (for test purposes), which can be altered by changing method initDbs in class BaseAbstractRedisServer . The cache is persisted every 100ms and the server is able to recover gracefully from any sudden or shutdown signals.

How to run

Please run the following command in your terminal to start an instance of simple-redis-server:

cd $PROJECT_DIR
./gradlew startServer --console=plain

NOTE: This application runs on port 6789 by default. You can change this port in class Server.

Tests

Test directory contains unit tests to ensure proper functionality of RedisServer, Cache and the newly impelemented DoublyLinkedList.

Client

You can run a client application which can communicate with a simple-redis-server instance, by following instruction in this repository:
