Distributed Blockchain Transactions (DBT)

This is a framework for working with SQL transactions in a distributed network. The framework allows you to compose SQL transactions of multiple queries on different nodes and execute them later.

To ensure the reliability of the transactions a ledger using blockchain is used to keep track on ongoing transactions and ensure queries within the transactions are consistent.

DBT Core

The core library containing the DBTModule to include in your Ratpack application.

The DBT module can be added like so:

bindings {
    module (DBTModule) { config ->
      config.ledger.remoteUrl = 'http://localhost:5050/ledger'
      config.executor.remoteUrl = 'http://localhost:5050/executor'
    }
}

DBT Demo

Demo application for testing the transactions.

The demo application has a database with one table LOGS which you can use to insert and select data from.

The demo can be run by running ./gradlew :dbt-demo:run after which the demo is running on http://localhost:5050

DBT Test

The test module contains all the integration tests for the module.
