Connect to Jira as an External Data Source using PolyBase

Use the CData ODBC Driver for Jira and PolyBase to create an external data source in SQL Server 2019 with access to live Jira data.

PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table. When paired with the CData ODBC Driver for Jira, you get access to your Jira data directly alongside your SQL Server data. This article walks through creating an external data source and external tables to grant access to live Jira data using T-SQL queries.

The CData ODBC drivers offer unmatched performance for interacting with live Jira data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to Jira, the driver pushes down supported SQL operations, like filters and aggregations, directly to Jira 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 Jira data, using a single query to pull data from distributed sources.

Connect to Jira

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 Jira Sys is created automatically).

To connect to JIRA, provide the User and Password. Additionally, provide the Url; for example, https://yoursitename.atlassian.net.

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

Create an External Data Source for Jira Data

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 Jira data.

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

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

Create an External Data Source for Jira

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

For Jira, 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_jira_source
WITH ( 
  LOCATION = 'odbc://SERVERNAME[:PORT]',
  CONNECTION_OPTIONS = 'DSN=CData Jira Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = jira_creds
);

Create External Tables for Jira

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to Jira data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for Jira. 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 Jira Issues would look similar to the following:

CREATE EXTERNAL TABLE Issues(
  Summary [nvarchar](255) NULL,
  TimeSpent [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='Issues',
  DATA_SOURCE=cdata_jira_source
);

Having created external tables for Jira 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 Jira, freeing up local resources and computing power.
