Getting Started with Scalar DB on DynamoDB

Overview​

This document briefly explains how you can get started with Scalar DB on DynamoDB with a simple electronic money application.

Install prerequisites​

Scalar DB is written in Java. So the following software is required to run it.

  • Oracle JDK 8 (OpenJDK 8) or higher
  • Other libraries used from the above are automatically installed through gradle

From here, we assume Oracle JDK 8 is properly installed in your local environment.

Configure Scalar DB​

The scalardb.properties (getting-started/scalardb.properties) file holds the configuration for Scalar DB. You need to update contact_points with AWS region, username with your AWS access key id, password with your AWS access secret key and storage with dynamo.

# Comma separated contact points
scalar.db.contact_points=<REGION>

# Port number for all the contact points. Default port number for each database is used if empty.
#scalar.db.contact_port=

# Credential information to access the database
scalar.db.username=<AWS_ACCESS_KEY_ID>
scalar.db.password=<AWS_ACCESS_SECRET_KEY>

# Storage implementation. Either cassandra or cosmos or dynamo or jdbc can be set. Default storage is cassandra.
scalar.db.storage=dynamo

Please follow Getting Started with Scalar DB to run the application.
