Table 4.1. .Net Client Library Connection Methods
| Method | Title |
|---|---|
object.new CouchbaseClient([ url ] [, username ] [, password ]) | Create connection to Couchbase Server |
| API Call | object.new CouchbaseClient([ url ] [, username ] [, password ]) | ||
| Asynchronous | no | ||
| Description | Create a connection to Couchbase Server with given parameters, such as node URL. The connection obtains the cluster configuration from the first host to which it has connected. Further communication operates directly with each node in the cluster as required. | ||
| Returns | (none) | ||
| Arguments | |||
string url | URL for Couchbase Server Instance, or node. | ||
string username | Username for Couchbase bucket. | ||
string password | Password for Couchbase bucket. | ||
The easiest way to specify a connection, or a pool of connections is
to provide it in the App.config file of your .Net
project. By doing so, you can change the connection information
without having to recompile. You can update
App.config in Visual Studio as follows:
<servers bucket="private" bucketPassword="private"> <add uri="http://10.0.0.33:8091/pools/default"/> <add uri="http://10.0.0.34:8091/pools/default"/> </servers>
You should change the URI above to point at your server by replacing
10.0.0.33 with the IP address or hostname of your Couchbase server
machine. Be sure you set your bucket name and password. You can also
set the connection to use the default bucket, by setting the bucket
attribute to default and leaving the
bucketPassword attribute empty. In this case we
have configured the server with a bucket named 'private' and with a
password 'private.'
Connections that you create with the .Net SDK are also thread-safe objects; for persisted connections, you can use a connection pool which contains multiple connection objects. You should create only a single static instance of a Couchbase client per bucket, in accordance with .Net framework. The persistent client will maintain connection pools per server node.
