接続の確立
コネクタ内で利用可能なオブジェクトは、"cdata.greenplum" モジュールからアクセスできます。モジュールのオブジェクトを直接使用するには:
- モジュールを以下のようにインポートします。
import cdata.greenplum as mod
- 接続を確立するには、以下のような適切な接続文字列を使用してコネクタオブジェクトからconnect() メソッドを呼び出します。
mod.connect("User=user;Password=admin;Database=dbname;Server=127.0.0.1;Port=5432")
Connecting to Greenplum
To connect to Greenplum, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you want to use to authenticate to the server. If the Database property is not specified, the 本製品 connects to the user's default database (it is the same name as the user).
Authenticating to Greenplum
The CData Python Connector for Greenplum supports the md5, password, Kerberos and SASL (particulary, SCRAM-SHA-256) authentication methods.The specific authentication method is setup in the pg_hba.conf file on the Greenplum Server. You can find instructions about authentication setup on the Greenplum Server here. The md5, password and SASL authentication methods do not require additional setup by the CData Python Connector for Greenplum.
Kerberos
The Greenplum Server initiates authentication with the Kerberos Server when the CData Python Connector for Greenplum attempts a connection. You need to setup Kerberos on the Greenplum Server to activate this authentication method. After you have Kerberos authentication setup on the Greenplum Server, see Kerberos の使用 for details on how to authenticate with Kerberos by the 本製品.
