My approach to the ['Build Your Own Redis'](https://app.codecrafters.io/courses/redis/) challenge.

## Features  

- **Basic Commands**: 

  - `GET`

  - `SET` (with TTL)

  - `PING`

  - `ECHO`  

- **Concurrency**: Supports multiple concurrent clients  

- **Persistence**: Loads RDB files and serves the content

- **Replication**:  

  - Performs replication handshake  

  - Propagates commands to replicas  

  - Supports the `WAIT` command  

- **Streams**:

  - Create streams

  - Support `XREAD` and `XRANGE` commands

  - Support blocking reads (`XREAD block`)

  - Support different type of queries (with `+`, `-`, `$`, partially/fully create IDs)

- **Transactions**:

  - `INCR` command

  - `MULTI` and `EXEC` commands

  - Multiple concurrent transactions with failures within transactions 

## RUN

- **Build**:

  - `go build -o redis app/*.go`

- **Basic execution**:

  - `./redis --port 5678`

- **Parse RDB**:

  - `./redis --dir ./redis-data/ --dbfilename dump.rdb --port 5678`

- **Run as replica**:

  - `./redis --port 1234 --replicaof "localhost 6379"`

  

After the server is running, you can connect to it via any Redis client, Including `redis-cli`;

Ex: `redis-cli xread block 10000 streams orange 0-110`.

**NOTE**: The current version fully supports RESP V2.
