# ZooKeeper Sandbox
This repository contains a basic example of Apache's ZooKeeper usage.
Made as a part of Distributed Systems course at the AGH University of Science and Technology.
**Language**: Kotlin
**UI**: Jetpack Compose
## Configuration
Before running, please make sure that you have read and configured
ZooKeeper server according to [these](scripts/README.md) instructions.
### Environment variables
| Name | Description | Default |
|---------------|---------------------------------------------------------------------------|------------------|
| `ZK_HOSTNAME` | Server's ip and port | `127.0.0.1:2181` |
| `ZK_EXT_APP` | An executable that will be launched/closed on node `/a` creation/deletion | `glxgears` |
## Usage
1. Start server
2. Execute
```bash
./gradlew run
```
3. Now execute some commands, e.g. `create /a`, `delete /a`, `create /a/b` etc
## Original task
Stworzyć aplikację w środowisku Zookeeper (Java, …) która wykorzystując mechanizm
obserwatorów (watches) umożliwia następujące funkcjonalności:
- Jeśli tworzony jest znode o nazwie "a" uruchamiana jest zewnętrzna aplikacja
graficzna (dowolna, określona w linii poleceń),
- Jeśli jest kasowany "a" aplikacja zewnętrzna jest zatrzymywana,
- Każde dodanie potomka do "a" powoduje wyświetlenie graficznej informacji na ekranie
o aktualnej ilości potomków.
- Dodatkowo aplikacja powinna mieć możliwość wyświetlenia całej struktury drzewa "a".
- Stworzona aplikacja powinna działać w środowisku "Replicated ZooKeeper".
