Explorer Scheduled Jobs

This repository executes tasks in a periodic sequence to precompute computationally intensive jobs.

👉 Check the Explorer repository to understand how the microservices work together

How to run

Following prerequisites are required to run the application:

• Java 17
• Redis
• Postgres (ledger-sync and explorer database)
• Ledger-sync (Ledgersync + Aggregate app + Postgres)

An example docker-compose script is provided in the example-infra directory. (This script only sets up Redis and Postgres, for a ledger-sync setup, please refer to the ledger-sync repository)

This can be used right away with the provided .env.example and adjusted as needed.

To start the needed Infrastructure, run:

# Start Redis and Postgres
docker-compose -f example-infra/docker-compose.yml up
# Additionally start Ledger Sync according to the docs in the ledger-sync repository 

To run the application via command line:

# Copy the .env.example to .env and adjust as needed
cp .env.example .env
# Build the application
source .env
mvn clean package
mvn spring-boot:run

• LEDGER_SYNC_FLYWAY_ENABLE: Ledger-sync Migrate schema, set true if this is the first time run app

• LEDGER_SYNC_AGG_HOST= Ledger-sync aggregate database host.

• LEDGER_SYNC_AGG_PORT= Ledger-sync aggregate database port

• LEDGER_SYNC_AGG_USER= Ledger-sync aggregate database username

• LEDGER_SYNC_AGG_PASSWORD= Ledger-sync aggregate database password
