The samples in this project demonstrate several uses of Amazon QLDB.
See Accessing Amazon QLDB for information on connecting to AWS.
The examples are written in Java 8 using the Gradle build tool. Java 8 must be installed to build the examples, however the Gradle wrapper is bundled in the project and does not need to be installed. Please see the link below for more detail to install Java 8 and information on Gradle:
The sample code creates a ledger with tables and indexes, and inserts some documents into those tables, among other things. Each of the examples in this project can be run in the following way:
Windows:
gradlew run -Dtutorial=CreateLedger
Unix:
./gradlew run -Dtutorial=CreateLedger
The above example will build the CreateLedger class with the necessary dependencies and create a ledger named:
vehicle-registration. You may run other examples after creating a ledger.
