This is a RESP compliant redis server only support RESP3.

Getting Started

cd /redis-server

./gradlew build

./gradlew run

1. Open command line interface
2. execute under command

nc localhost 6379

Then cli can communicate with the redis-server.

interaction between the client and the server

A client sends the Redis server an array consisting of only bulk strings.
A Redis server replies to clients, sending any valid RESP data type as a reply.

So, for example, a typical interaction could be the following.

The client sends the command SET key value NX. Then the server replies with simple reply(OK) as in the following example (C: is the client, S: the server).

C: *4\r\n<br>
C: $3\r\n<br>
C: SET\r\n<br>
C: $3\r\n<br>
C: key\r\n<br>
C: $5\r\n<br>
C: value\r\n<br>
C: $2\r\n<br>
C: NX

S: :+OK\r\n<br>

As usual, we separate different parts of the protocol with newlines(\r\n) for simplicity, but the actual interaction is the client sending *4$3SET$3key$5value$2NX as a whole.
