You can query the database within the application and you can check the operation of batch processing by selecting records that cause batch processing to fail.

## Run on local

### Requirements

- PostgresSQL

### Configure environment's variables

Please define 3 environment variables for the database connection:

```sh
export $DB_ENDPOINT=localhost
export $DB_USERNAME=<your_db_username>
export $DB_PASSWORD=<your_db_password>
```

### Initialize table and add sample data

The configuration of `spring.sqll.init.mode=always` is set in `src/resources/application.properties` that will always call `src/main/resources/data.sql` and `src/main/resources/schema.sql` to initialize the database.

These settings are for the purpose of this sample, please consider separately ways to initialize the database and perform the migration in production enviroments.

```sh
./gradlew bootRun
```
