# Scheduling jobs in Spring with Quartz Clustered mode - PoC
This repository demonstrates how to schedule jobs in Spring Boot application with Quartz Clustered mode.
## Features
* Retry Pattern With Exponential Back-Off
* Quartz Clustered Mode
* PostgreSQL DB
* Flyway
* Docker / Docker Compose
## Getting Started
### Prerequisites:
* Java 11
* Docker
### Installation
Build docker image
```shell
./gradlew bootBuildImage
```
### Usage:
1. Start services.
```shell
cd docker
docker compose up -d
```
2. Check if all services are running.
```shell
docker compose ps
```
3. Schedule new todo job.
```shell
curl --location --request POST 'http://localhost:8080/api/v1/todos' \
--header 'Content-Type: application/json' \
--data-raw '{
"id": 2
}'
```
4. Simulate failure.
```shell
curl --location --request POST 'http://localhost:8080/api/v1/todos' \
--header 'Content-Type: application/json' \
--data-raw '{
"id": 1
}'
```
5. Check logs and verify if retry with exponential backoff works.
```shell
docker compose logs -f

```
6. Open [Adminer](http://localhost:8081/) and investigate database structure. Connection details:
* System: PostgresSQL
* Server: db
* Username: demo
* Password: demo
* Database: demo
7. Stop services.
```shell
docker compose down -v
```
