Template for the HighLoad course

This project is based on Tiny Event Sourcing library

Run PostgreSql

This example uses Postgres as an implementation of the Event store. You can see it in pom.xml:

<dependency>
    <groupId>ru.quipy</groupId>
    <artifactId>tiny-postgres-event-store-spring-boot-starter</artifactId>
    <version>${tiny.es.version}</version>
</dependency>

Thus, you have to run Postgres in order to test this example. Postgres service is included in docker-compose file that we have in the root of the project.

Run the infrastructure

Set of the services you need to start developing and testing process is following:

• Bombardier - service that is in charge of emulation the store's clients activity (creates the incoming load). Also serves as a third-party payment system.
• Postgres DBMS
• Prometheus + Grafana - metrics collection and visualization services

You can run all beforementioned services by the following command:

docker compose -f docker-compose.yml up

Run the application

To make the application run you can start the main class OnlineShopApplication. It is not being launched as a docker contained to simplify and speed up the devevopment process as it is easier for you to refactor the application and re-run it immediately in the IDE.

If you want to pull changes from the main repository into your fork

The command git remote -v should include the following lines:

upstream        https://github.com/andrsuh/high-load-course.git (fetch)
upstream        https://github.com/andrsuh/high-load-course.git (push)

If not, add the upstream remote: git remote add upstream https://github.com/andrsuh/high-load-course.git

To pull changes from the main repository, run the following commands:

git fetch upstream
# switch to the main branch of your fork. Make sure the branch has no uncommitted changes to avoid conflicts
git checkout main 
# merge changes from the main repository into your main branch
git merge upstream/main
