Chapter 1. Remote caches
Deploy multiple Data Grid Server instances to create remote cache clusters that give you a fault-tolerant and scalable data tier with high-speed access from Hot Rod and REST clients.
1.1. Remote cache tutorials
To run these tutorials you need at least one locally running instance of Data Grid Server. Each tutorial will try to connect to a running server in localhost:11222 with admin/password credentials. However, if a Docker instance is found, and the server is not running, tutorials will spin up a local server with Testcontainers.
You can download the distribution and run the following commands:
./bin/cli.sh user create admin -p "password" ./bin/server.sh
$ ./bin/cli.sh user create admin -p "password"
$ ./bin/server.sh
Data Grid Server enables authentication and authorization by default. Creating a user named admin gives you administrative access to Data Grid Server.
Building and running remote cache tutorials
You can build and run remote cache tutorials directly in your IDE or from the command line as follows:
mvn -s /path/to/maven-settings.xml clean package exec:exec
$ mvn -s /path/to/maven-settings.xml clean package exec:exec1.2. Hot Rod Java client tutorials
- Data Grid requires Java 11 at a minimum. However, Hot Rod Java clients running in applications that require Java 8 can continue using older versions of client libraries.
