Examples of voldemort.client.protocol.admin.AdminClient

voldemort.client.protocol.admin.AdminClient
AdminClient is intended for administrative functionality that is useful and often needed, but should be used sparingly (if at all) at the application level.
Some of the uses of AdminClient include
- Extraction of data for backups
- Extraction of all keys
- Bulk loading entries
- Migrating partitions
- Get/Update metadata info from selective Nodes
- Used extensively by rebalancing (dynamic node addition/deletion) feature (presently in development).


        storeDefs = new StoreDefinitionsMapper().readStoreList(new File(storesXmlfile));


        Properties adminProperties = new Properties();
        adminProperties.setProperty("max_connections", "20");
        adminClient = new AdminClient(cluster,
                                      new AdminClientConfig(adminProperties),
                                      new ClientConfig());


        Node node = cluster.getNodeById(0);
        String bootstrapUrl = "tcp://" + node.getHost() + ":" + node.getSocketPort();
