Chapter 13. 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
13.1. 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" security: authorization: ~
13.2. 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
-
Open
127.0.0.1:11222/console/
in any browser. - Select Create Cache and follow the steps as Data Grid Console guides you through the process.
13.3. 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
Start the CLI.
bin/cli.sh
-
Run the
connect
command and enter your username and password when prompted. 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
List all remote caches with the
ls
command.ls caches mycache
View cache configuration with the
describe
command.describe caches/mycache
13.4. 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#, 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 theConfigurationBuilder
. -
Set the
configuration
orconfiguration_uri
properties in thehotrod-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
If the name of your remote cache contains the .
character, you must enclose it in square brackets when using hotrod-client.properties
files.
13.5. 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.
