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 = '<ledger host>:<ledger port>/ledger'
      config.executor.remoteUrl = '<executor host>:<executor port>/executor'
    }
}

DBT Test

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

Docker

There are two projects available for building the executor and the ledger as docker images.

• docker-ledger - Run the ledger as a docker image
• docker-executor - Run the executor as a docker image

For more information how to run and configure them see their corresponding READMEs.
