PolyBase で外部データソースとしてSuiteCRM を連携利用

CData ODBC Driver for SuiteCRM とSQL Server 2019 のPolyBase を使って、リアルタイムSuiteCRM data に外部データソースとしてアクセス。

SQL Server のPolyBase は、データベーステーブルをクエリするTransact-SQL シンタックスを使って、外部データにクエリする仕組みです。 CData ODBC Drivers for SuiteCRM data を組み合わせて使うことで、SQL Server データと同じようにSuiteCRM data へのアクセスが可能です。 本記事では、PolyBase 外部データソースへのSuiteCRM data の設定から、T-SQL クエリを使ったSuiteCRM data へのアクセスを行います。

The CData ODBC drivers offer unmatched performance for interacting with live SuiteCRM data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to SuiteCRM, the driver pushes down supported SQL operations, like filters and aggregations, directly to SuiteCRM and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. And with PolyBase, you can also join SQL Server data with SuiteCRM data, using a single query to pull data from distributed sources.

SuiteCRM への接続

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. To create an external data source in SQL Server using PolyBase, configure a System DSN (CData SuiteCRM Sys is created automatically).

次の接続プロパティを設定すると、V4.1 API 経由でSuiteCRM データに接続できます。

  • Schema:suitecrmv4 に設定。
  • Url:SuiteCRM アプリケーションに紐づいているURL(例:http://suite.crm.com)に設定。
  • User:SuiteCRM に紐づいているユーザーに設定。
  • Password:SuiteCRM に紐づいているパスワードに設定。

SuiteCRM メタデータの取得は高負荷になる可能性があることに注意してください。メタデータのキャッシュ で説明しているように、メタデータをローカルに格納することをお勧めします。

Click "Test Connection" to ensure that the DSN is connected to SuiteCRM properly. Navigate to the Tables tab to review the table definitions for SuiteCRM.

SuiteCRM Data の外部データソースの作成

After configuring the connection, you need to create a master encryption key and a credential database for the external data source.

Creating a Master Encryption Key

Execute the following SQL command to create a new master key, 'ENCRYPTION,' to encrypt the credentials for the external data source.

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password';

Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to SuiteCRM data.

NOTE: IDENTITY and SECRET correspond with the User and Password properties for SuiteCRM.

CREATE DATABASE SCOPED CREDENTIAL suitecrm_creds
WITH IDENTITY = 'username', SECRET = 'password';

Create an External Data Source for SuiteCRM

Execute the following SQL command to create an external data source for SuiteCRM with PolyBase, using the DSN and credentials configured earlier.

For SuiteCRM, set SERVERNAME to 'localhost' or '127.0.0.1' and leave PORT empty. PUSHDOWN is set to ON by default, meaning the ODBC Driver can leverage server-side processing for complex queries.

CREATE EXTERNAL DATA SOURCE cdata_suitecrm_source
WITH ( 
  LOCATION = 'odbc://SERVERNAME[:PORT]',
  CONNECTION_OPTIONS = 'DSN=CData SuiteCRM Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = suitecrm_creds
);

SuiteCRM のExternal Table を作成

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to SuiteCRM data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for SuiteCRM. You can refer to the Tables tab of the DSN Configuration Wizard to see the table definition.

Sample CREATE TABLE Statement

The statement to create an external table based on a SuiteCRM Accounts would look similar to the following:

CREATE EXTERNAL TABLE Accounts(
  Name [nvarchar](255) NULL,
  Industry [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='Accounts',
  DATA_SOURCE=cdata_suitecrm_source
);

Having created external tables for SuiteCRM in your SQL Server instance, you are now able to query local and remote data simultaneously. Thanks to built-in query processing in the CData ODBC Driver, you know that as much query processing as possible is being pushed to SuiteCRM, freeing up local resources and computing power.
