Chapter 12. Creating remote caches

When you create remote caches at runtime, Data Grid Server synchronizes your configuration across the cluster so that all nodes have a copy. For this reason you should always create remote caches dynamically with the following mechanisms:

  • Data Grid Console
  • Data Grid Command Line Interface (CLI)
  • Hot Rod or HTTP clients

12.1. Default Cache Manager

Data Grid Server provides a default Cache Manager that controls the lifecycle of remote caches. Starting Data Grid Server automatically instantiates the Cache Manager so you can create and delete remote caches and other resources like Protobuf schema.

After you start Data Grid Server and add user credentials, you can view details about the Cache Manager and get cluster information from Data Grid Console.

  • Open 127.0.0.1:11222 in any browser.

You can also get information about the Cache Manager through the Command Line Interface (CLI) or REST API:

CLI

Run the describe command in the default container.

[//containers/default]> describe
REST
Open 127.0.0.1:11222/rest/v2/cache-managers/default/ in any browser.

Default Cache Manager configuration

XML

<infinispan>
  <!-- Creates a Cache Manager named "default" and enables metrics. -->
  <cache-container name="default"
                   statistics="true">
     <!-- Adds cluster transport that uses the default JGroups TCP stack. -->
     <transport cluster="${infinispan.cluster.name:cluster}"
                stack="${infinispan.cluster.stack:tcp}"
                node-name="${infinispan.node.name:}"/>
     <!-- Requires user permission to access caches and perform operations. -->
     <security>
        <authorization/>
     </security>
  </cache-container>
</infinispan>

JSON

{
  "infinispan" : {
    "jgroups" : {
      "transport" : "org.infinispan.remoting.transport.jgroups.JGroupsTransport"
    },
    "cache-container" : {
      "name" : "default",
      "statistics" : "true",
      "transport" : {
        "cluster" : "cluster",
        "node-name" : "",
        "stack" : "tcp"
      },
      "security" : {
        "authorization" : {}
      }
    }
  }
}

YAML

infinispan:
  jgroups:
    transport: "org.infinispan.remoting.transport.jgroups.JGroupsTransport"
  cacheContainer:
    name: "default"
    statistics: "true"
    transport:
      cluster: "cluster"
      nodeName: ""
      stack: "tcp"

12.2. Creating caches with Data Grid Console

Use Data Grid Console to create remote caches in an intuitive visual interface from any web browser.

Prerequisites

  • Create a Data Grid user with admin permissions.
  • Start at least one Data Grid Server instance.
  • Have a Data Grid cache configuration.

Procedure

  1. Open 127.0.0.1:11222/console/ in any browser.
  2. Select Create Cache and follow the steps as Data Grid Console guides you through the process.

12.3. Creating remote caches with the Data Grid CLI

Use the Data Grid Command Line Interface (CLI) to add remote caches on Data Grid Server.

Prerequisites

  • Create a Data Grid user with admin permissions.
  • Start at least one Data Grid Server instance.
  • Have a Data Grid cache configuration.

Procedure

  1. Start the CLI and enter your credentials when prompted.

    bin/cli.sh
  2. Use the create cache command to create remote caches.

    For example, create a cache named "mycache" from a file named mycache.xml as follows:

    create cache --file=mycache.xml mycache

Verification

  1. List all remote caches with the ls command.

    ls caches
    mycache
  2. View cache configuration with the describe command.

    describe caches/mycache

12.4. Creating remote caches from Hot Rod clients

Use the Data Grid Hot Rod API to create remote caches on Data Grid Server from Java, C++, .NET/C{hash}, JS clients and more.

This procedure shows you how to use Hot Rod Java clients that create remote caches on first access. You can find code examples for other Hot Rod clients in the Data Grid Tutorials.

Prerequisites

  • Create a Data Grid user with admin permissions.
  • Start at least one Data Grid Server instance.
  • Have a Data Grid cache configuration.

Procedure

  • Invoke the remoteCache() method as part of your the ConfigurationBuilder.
  • Set the configuration or configuration_uri properties in the hotrod-client.properties file on your classpath.

ConfigurationBuilder

File file = new File("path/to/infinispan.xml")
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.remoteCache("another-cache")
       .configuration("<distributed-cache name=\"another-cache\"/>");
builder.remoteCache("my.other.cache")
       .configurationURI(file.toURI());

hotrod-client.properties

infinispan.client.hotrod.cache.another-cache.configuration=<distributed-cache name=\"another-cache\"/>
infinispan.client.hotrod.cache.[my.other.cache].configuration_uri=file:///path/to/infinispan.xml

Important

If the name of your remote cache contains the . character, you must enclose it in square brackets when using hotrod-client.properties files.

12.5. Creating remote caches with the REST API

Use the Data Grid REST API to create remote caches on Data Grid Server from any suitable HTTP client.

Prerequisites

  • Create a Data Grid user with admin permissions.
  • Start at least one Data Grid Server instance.
  • Have a Data Grid cache configuration.

Procedure

  • Invoke POST requests to /rest/v2/caches/<cache_name> with cache configuration in the payload.
