    - * Most likely you want to start out by using the {@link #connect(String, String, String)} entry point. For more - * advanced options you want to use the {@link #connect(String, ClusterOptions)} method. The entry point that allows - * overriding the seed nodes ({@link #connect(Set, ClusterOptions)} is only needed if you run a couchbase cluster - * at non-standard ports. - *

    - * See the individual connect methods for more information, but here is a snippet to get you off the ground quickly. It - * assumes you have Couchbase running locally and the "travel-sample" sample bucket loaded: - * 

    - * //Connect and open a bucket
- * Cluster cluster = Cluster.connect("127.0.0.1","Administrator","password");
- * Bucket bucket = cluster.bucket("travel-sample");
- * Collection collection = bucket.defaultCollection();
- *
- * // Perform a N1QL query
- * QueryResult queryResult = cluster.query("select * from `travel-sample` limit 5");
- * System.out.println(queryResult.rowsAsObject());
- *
- * // Perform a KV request and load a document
- * GetResult getResult = collection.get("airline_10");
- * System.out.println(getResult);
- *
    - *

    - * When the application shuts down (or the SDK is not needed anymore), you are required to call {@link #disconnect()}. - * If you omit this step, the application will terminate (all spawned threads are daemon threads) but any operations - * or work in-flight will not be able to complete and lead to undesired side-effects. Note that disconnect will also - * shutdown all associated {@link Bucket buckets}. - *

    - * Cluster-level operations like {@link #query(String)} will not work unless at leas one bucket is opened against a - * pre 6.5 cluster. If you are using 6.5 or later, you can run cluster-level queries without opening a bucket. All - * of these operations are lazy, so the SDK will bootstrap in the background and service queries as quickly as possible. - * This also means that the first operations might be a bit slower until all sockets are opened in the background and - * the configuration is loaded. If you want to wait explicitly, you can utilize the {@link #waitUntilReady(Duration)} - * method before performing your first query. - *

    - * The SDK will only work against Couchbase Server 5.0 and later, because RBAC (role-based access control) is a first - * class concept since 3.0 and therefore required. - */ -// todo gpx as per discussion with miker - if required, ClusterInterface will be added to the SDK instead -public class Cluster implements ClusterInterface { - - /** - * Holds the underlying async cluster reference. - */ - private final AsyncCluster asyncCluster; - - /** - * Holds the adjacent reactive cluster reference. - */ - private final ReactiveCluster reactiveCluster; - - /** - * The search index manager manages search indexes. - */ - private final SearchIndexManager searchIndexManager; - - /** - * The user manager manages users and groups. - */ - private final UserManager userManager; - - /** - * The bucket manager manages buckets and allows to flush them. - */ - private final BucketManager bucketManager; - - /** - * Allows to manage query indexes. - */ - private final QueryIndexManager queryIndexManager; - - /** - * Allows to manage analytics indexes. - */ - private final AnalyticsIndexManager analyticsIndexManager; - - /** - * Allows to manage eventing functions. - */ - private final EventingFunctionManager eventingFunctionManager; - - /** - * Stores already opened buckets for reuse. - */ - private final Map bucketCache = new ConcurrentHashMap<>(); - - /** - * Connect to a Couchbase cluster with a username and a password as credentials. - *

    - * This is the simplest (and recommended) method to connect to the cluster if you do not need to provide any - * custom options. - *

    - * The first argument (the connection string in its simplest form) is used to supply the hostnames of the cluster. In - * development it is OK to only pass in one hostname (or IP address), but in production we recommend passing in at - * least 3 nodes of the cluster (comma separated). The reason is that if one or more of the nodes are not reachable - * the client will still be able to bootstrap (and your application will become more resilient as a result). - *

    - * Here is how you specify one node to use for bootstrapping: - * 

    -   * Cluster cluster = Cluster.connect("127.0.0.1", "user", "password"); // ok during development
-   *
    - * This is what we recommend in production: - * 
    -   * Cluster cluster = Cluster.connect("host1,host2,host3", "user", "password"); // recommended in production
-   *
    - * It is important to understand that the SDK will only use the bootstrap ("seed nodes") host list to establish an - * initial contact with the cluster. Once the configuration is loaded this list is discarded and the client will - * connect to all nodes based on this configuration. - *

    - * This method will return immediately and the SDK will try to establish all the necessary resources and connections - * in the background. This means that depending on how fast it can be bootstrapped, the first couple cluster-level - * operations like {@link #query(String)} will take a bit longer. If you want to wait explicitly until those resources - * are available, you can use the {@link #waitUntilReady(Duration)} method before running any of them: - * 

    -   * Cluster cluster = Cluster.connect("host1,host2,host3", "user", "password");
-   * cluster.waitUntilReady(Duration.ofSeconds(5));
-   * QueryResult result = cluster.query("select * from bucket limit 1");
-   *
    - * - * @param connectionString connection string used to locate the Couchbase cluster. - * @param username the name of the user with appropriate permissions on the cluster. - * @param password the password of the user with appropriate permissions on the cluster. - * @return the instantiated {@link Cluster}. - */ - public static Cluster connect(final String connectionString, final String username, final String password) { - return connect(connectionString, clusterOptions(PasswordAuthenticator.create(username, password))); - } - - /** - * Connect to a Couchbase cluster with custom options. - *

      • - *
    • Or a custom {@link Authenticator}
      • - *
    - * needs to be provided. - *

    - * A custom environment can be passed in like this: - * 

    -   * // on bootstrap:
-   * ClusterEnvironment environment = ClusterEnvironment.builder().build();
-   * Cluster cluster = Cluster.connect(
-   *   "127.0.0.1",

-   * );
-   *
-   * // on shutdown:
-   * cluster.disconnect();
-   * environment.shutdown();
-   *
    - * It is VERY important to shut down the environment when being passed in separately (as shown in - * the code sample above) and AFTER the cluster is disconnected. This will ensure an orderly shutdown - * and makes sure that no resources are left lingering. - *

    - * If you want to pass in a custom {@link Authenticator}, it is likely because you are setting up certificate-based - * authentication instead of using a username and a password directly. Remember to also enable TLS. - * 

    -   * ClusterEnvironment environment = ClusterEnvironment
-   *   .builder()
-   *   .securityConfig(SecurityConfig.enableTls(true))
-   *   .build();
-   *
-   * Authenticator authenticator = CertificateAuthenticator.fromKey(...);
