Couchbase .NET SDK 2.3.9 Now Available!

Today we're releasing version 2.3.9 of the Couchbase .NET SDK. In this release we have a mixture of new features and bug fixes; including Data Structure API, Cluster Level Authentication and Cluster Level Query support. Also, in case you missed it, we have a Developer Preview of .NET Core support 여기.

새로운 기능 및 변경 사항

We follow semantic versioning, meaning we increment the dot-minor number when adding features. We add low-risk features in maintenance releases with uncommitted interface stability so you as a developer can easily gain access to new features. The features mentioned here are all uncommitted, but should be promoted to committed in the next dot-minor release. See 여기 를 참조하여 .NET SDK의 인터페이스에 대해 설명하세요.

Data Structure API

Many developers utilise common data structures such as sets and lists in their applications and need to store and retrieve them regularly. We have added Couchbase backed JSON structures to make this process easier where changes in state are automatically persisted into the server.

The data types we have added support for are:

설정
목록
사전
대기열

A more complete introduction of the new Data Structure API will be available in another blog soon.

Cluster Level Authentication

Up until now authentication has been handled in the SDK at the bucket level. This meant that the bucket password was supplied when executing the GetBucket method against the bucket. With the introduction of Cluster Level Queries and more advanced forms of security coming in future releases of Couchbase Server, an improved mechanism is needed.

Cluster Level Authentication enables you to configure the authentication for each bucket directly in the cluster object where it is cached and reused efficiently. An example of setting up the credentials when building the cluster object is below.

var credentials = new ClusterCredentials
{
    ClusterUsername = "Administrator",
    ClusterPassword = "secret",
    BucketCredentials = new Dictionary<string, string>
    {
        { "secured", "password" } // bucketName, bucketPassword
    }
};

var cluster = new Cluster();
cluster.Authenticate(credentials);

var bucket = cluster.OpenBucket("secured");
// notice no password was passed in as it’s used from the credentials

var 자격 증명 = new ClusterCredentials

{

ClusterUsername = "관리자",

ClusterPassword = "비밀",

BucketCredentials = new 사전<문자열, 문자열>

{

{ "secured", "비밀번호" } // bucketName, bucketPassword

}

};

var 클러스터 = new 클러스터();

클러스터.인증(자격 증명);

var 버킷 = 클러스터.OpenBucket("secured");

// notice no password was passed in as it’s used from the credentials

Remember the Cluster should be a long lived object, typically set up when your application first starts and 클러스터 도우미 is a nice way to manage the lifetime of your cluster object.

Cluster Level Query

When a N1QL query is submitted, it is up to the query nodes in the cluster to interpret the statement and execute the query. It doesn’t need to be executed under the context of a particular bucket because the query statement includes the bucket name. To help make this easier we’ve copied the Query and QueryAsync API onto the ICluster interface so you can now execute N1QL queries with the Cluster object directly. An example of using the new cluster level Query API is below:

var config = new ClientConfiguration
{
     Servers = new List<Uri> {new Uri("http://127.0.0.1")}
};
var cluster = new Cluster(config);
var result = cluster.Query<Person>("SELECT * FROM `default` WHERE type = &apos;person&apos;;");

var 구성 = new 클라이언트 구성

{

서버 = new 목록<Uri> {new Uri("http://127.0.0.1")}

};

var 클러스터 = new 클러스터(구성);

var 결과 = 클러스터.쿼리<사람>("SELECT * FROM `default` WHERE type = 'person';");

FTS Update

We've been working on improving support for the upcoming FTS (Full Text Search) and consolidating the implementations across the different SDKs. There have been a number of bugs fixed to ensure the SDK has complete support for when the feature goes GA in Couchbase Server 4.6.
