11.12. Configure the Interface Using Connectors

Red Hat JBoss Data Grid supports three connector types, namely:
  • The hotrod-connector element, which defines the configuration for a Hot Rod based connector.
  • The memcached-connector element, which defines the configuration for a memcached based connector.
  • The rest-connector element, which defines the configuration for a REST interface based connector.

11.12.1. Configure Hot Rod Connectors
リンクのコピー

The following procedure describes the attributes used to configure the Hot Rod connector in Red Hat JBoss Data Grid's Remote Client-Server Mode. Both the hotrod-connector and topology-state-transfer elements must be configured based on the following procedure.

Procedure 11.1. Configuring Hot Rod Connectors for Remote Client-Server Mode

  1. The hotrod-connector Element

    The hotrod-connector element defines the configuration elements for use with Hot Rod.

    1. The socket-binding Parameter

      The socket-binding parameter specifies the socket binding port used by the Hot Rod connector. This is a mandatory parameter. 
      <subsystem xmlns="urn:infinispan:server:endpoint:6.0">
      <hotrod-connector socket-binding="hotrod" />

    2. The cache-container Parameter

      The cache-container parameter names the cache container used by the Hot Rod connector. This is a mandatory parameter. 
      <subsystem xmlns="urn:infinispan:server:endpoint:6.0">
      <hotrod-connector socket-binding="hotrod"
                        cache-container="local" />
      Copy to Clipboard Toggle word wrap

    3. The worker-threads Parameter

      The worker-threads parameter specifies the number of worker threads available for the Hot Rod connector. The default value for this parameter is the number of cores available multiplied by two. This is an optional parameter. 
      <subsystem xmlns="urn:infinispan:server:endpoint:6.0">
      <hotrod-connector socket-binding="hotrod"
                        cache-container="local" 
                        worker-threads="${VALUE}" />
      Copy to Clipboard Toggle word wrap

    4. The idle-timeout Parameter

      The idle-timeout parameter specifies the time (in milliseconds) the connector can remain idle before the connection times out. The default value for this parameter is -1, which means that no timeout period is set. This is an optional parameter. 
      <subsystem xmlns="urn:infinispan:server:endpoint:6.0">
      <hotrod-connector socket-binding="hotrod"
                        cache-container="local" 
                        worker-threads="${VALUE}" 
                        idle-timeout="${VALUE}"/>
      Copy to Clipboard Toggle word wrap

    5. The tcp-nodelay Parameter

      The tcp-nodelay parameter specifies whether TCP packets will be delayed and sent out in batches. Valid values for this parameter are true and false. The default value for this parameter is true. This is an optional parameter.
