This is a simple lagom application which is used to create user and fetch the details of existing users.
Steps to follow to run this application:
- Open the terminal.
- Clone the project
git clone git@github.com:DivyaDua/lagom-persistent-read-side.git. cd lagom-persistent-read-side.- Execute
sbt clean compile. - Run the cassandra on your localhost, since embedded cassandra is being disabled here.
- Run the application using
sbt runAll.
You can check which services are up by hitting http://localhost:8000/services. There, you can see that along with cassandra and kafka, service named 'user_service' is also running. And you can check through cqlsh(cassandra query language shell) that keyspace named user is created having usertable.
