Key-value

Redis:In computing, Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.

Check the code

This part has two configuration files and seven classes

• src/main/resources/META-INF/beans.xml: CDI configuration file

• src/main/resources/diana-redis.properties: Database connection configuration file

• org.jnosql.demo.key.BucketManagerProducer: Connection handler

• org.jnosql.demo.key.User: This class is a org.jnosql.artemis.Entity to model a User

• org.jnosql.demo.key.UserBuilder: builder to create a User entity

• org.jnosql.demo.key.UserEvent

• org.jnosql.demo.key.UserRepository Artemis Repository for User entity

• org.jnosql.demo.key.App This class will be used to make the exercises.

This class creates and persist into Diana-redis one user with two telephone numbers whith username, name and then queries it:

	private static final User USER = User.builder()
         				.withPhones(Arrays.asList("234", "432"))
            				.withUsername("username")
            				.withName("Name")
            				.build();

• org.jnosql.demo.key.App2 This class will be used to make the exercises.

This class creates and persist into Diana-redis one user with two telephone numbers whith username, name and then queries it:

	private static final User USER = User.builder()
         				.withPhones(Arrays.asList("234", "432"))
            				.withUsername("username")
            				.withName("Name")
            				.build();

Start the workshop

1. Run the Redis Docker instance

   docker run --name redis-instance -p 6379:6379 -d redis
   

2. Compile the project via Maven

   mvn compile
   

3. Run the project via Maven

   mvn exec:java -Dexec.mainClass="org.jnosql.demo.key.App"
   
   mvn exec:java -Dexec.mainClass="org.jnosql.demo.key.App2"
   

Time to practice

Now, It is time you explore the code: add new persons, more relationships, and create new queries. Also you can try to an create your own entities that can be used to respond some questions, next some ideas:

• Create a database to handle JUG information using Redis
• Create, Retrieve and Update JUG information
• Where the JUG name is the unique value.
