Jira Source Connector for Confluent Cloud¶

The fully-managed Jira Source connector for Confluent Cloud is used to move data from Jira to an Apache Kafka® topic. This connector polls data from Jira through Jira v2 APIs, converts data into Kafka records, and moves the records into the Kafka topic. Each row from a Jira table is converted into exactly one Kafka record.

Note

This is a Quick Start for the fully-managed cloud connector. If you are installing the connector locally for Confluent Platform, see Jira Source Connector for Confluent Platform.

Features¶

The Jira Source connector supports the following features:

At least once delivery: The connector guarantees that records are delivered at least once to the Kafka topic (if the file row parsed is valid).
Supports multiple tasks: The connector supports running one or more tasks. More tasks may improve performance. One Jira resource (table) is covered by one task only.
Offset management capabilities: Supports offset management. For more information, see Manage custom offsets.

For more information and examples to use with the Confluent Cloud API for Connect, see the Confluent Cloud API for Managed and Custom Connectors section.

Limitations¶

Be sure to review the following information.

For connector limitations, see Jira Source Connector limitations.
If you plan to use one or more Single Message Transforms (SMTs), see SMT Limitations.
If you plan to use Confluent Cloud Schema Registry, see Schema Registry Enabled Environments.

Jira Resources¶

The connector can fetch from the following resources:

changelogs : See Get changelogs.
issue_comments : See Get comments.
issue_transitions : See Get transitions.
issues : See Get issue.
project_categories : See Project categories.
project_types : See Project types.
projects : See Get projects paginated.
resolutions : See Get resolutions.
roles : See Get project roles for project.

worklogs : See Get issue worklogs.

Manage custom offsets¶

You can manage the offsets for this connector. Offsets provide information on the point in the system from which the connector is accessing data. For more information, see Manage Offsets for Fully-Managed Connectors in Confluent Cloud.

To manage offsets:

Manage offsets using Confluent Cloud APIs. For more information, see Cluster API reference.

To get the current offset, make a GET request that specifies the environment, Kafka cluster, and connector name.

GET /connect/v1/environments/{environment_id}/clusters/{kafka_cluster_id}/connectors/{connector_name}/offsets
Host: https://api.confluent.cloud

Response:

Successful calls return HTTP 200 with a JSON payload that describes the offset.

{
    "id": "lcc-example123",
    "name": "{connector_name}",
    "offsets": [
        {
           "partition": {
           "name": "users"
           },
           "offset": {
           "date_updated": null
           }
        },
        {
           "partition": {
           "name": "projects"
           },
           "offset": {
           "date_updated": null
           }
        }
     ],
    "metadata": {
        "observed_at": "2024-03-28T17:57:48.139635200Z"
    }
}

Responses include the following information:

The position of latest offset.
The observed time of the offset in the metadata portion of the payload. The observed_at time indicates a snapshot in time for when the API retrieved the offset. A running connector is always updating its offsets. Use observed_at to get a sense for the gap between real time and the time at which the request was made. By default, offsets are observed every minute. Calling GET repeatedly will fetch more recently observed offsets.
Information about the connector.

To update the offset, make a POST request that specifies the environment, Kafka cluster, and connector name. Include a JSON payload that specifies new offset and a patch type.

POST /connect/v1/environments/{environment_id}/clusters/{kafka_cluster_id}/connectors/{connector_name}/offsets/request
Host: https://api.confluent.cloud

{
   "type": "PATCH",
   "offsets": [
      {
         "partition": {
         "name": "users"
         },
         "offset": {
         "date_updated": 1618184736
         }
      },
      {
         "partition": {
         "name": "projects"
         },
         "offset": {
         "date_updated": 1618184736
         }
      }
   ]
}

Considerations:

You can only make one offset change at a time for a given connector.
This is an asynchronous request. To check the status of this request, you must use the check offset status API. For more information, see Get the status of an offset request.
For source connectors, the connector attempts to read from the position defined by the requested offsets.

Response:

Successful calls return HTTP 202 Accepted with a JSON payload that describes the offset.

{
    "id": "lcc-example123",
    "name": "{connector_name}",
    "offsets": [
        {
           "partition": {
           "name": "issues"
           },
           "offset": {
           "date_updated": 1618184736
           }
        }
     ],
    "requested_at": "2024-03-28T17:58:45.606796307Z",
    "type": "PATCH"
}

Responses include the following information:

The requested position of the offsets in the source.
The time of the request to update the offset.
Information about the connector.

To delete the offset, make a POST request that specifies the environment, Kafka cluster, and connector name. Include a JSON payload that specifies the delete type.

 POST /connect/v1/environments/{environment_id}/clusters/{kafka_cluster_id}/connectors/{connector_name}/offsets/request
 Host: https://api.confluent.cloud

{
  "type": "DELETE"
}

Considerations:

Delete requests delete the offset for the provided partition and reset to the base state. A delete request is as if you created a fresh new connector.
This is an asynchronous request. To check the status of this request, you must use the check offset status API. For more information, see Get the status of an offset request.
Do not issue delete and patch requests at the same time.
For source connectors, the connector attempts to read from the position defined in the base state.

Response:

Successful calls return HTTP 202 Accepted with a JSON payload that describes the result.

{
  "id": "lcc-example123",
  "name": "{connector_name}",
  "offsets": [],
  "requested_at": "2024-03-28T17:59:45.606796307Z",
  "type": "DELETE"
}

Responses include the following information:

Empty offsets.
The time of the request to delete the offset.
Information about Kafka cluster and connector.
The type of request.

To get the status of a previous offset request, make a GET request that specifies the environment, Kafka cluster, and connector name.

GET /connect/v1/environments/{environment_id}/clusters/{kafka_cluster_id}/connectors/{connector_name}/offsets/request/status
Host: https://api.confluent.cloud

Considerations:

The status endpoint always shows the status of the most recent PATCH/DELETE operation.

Response:

Successful calls return HTTP 200 with a JSON payload that describes the result. The following is an example of an applied patch.

{
   "request": {
      "id": "lcc-example123",
      "name": "{connector_name}",
      "offsets": [
         {
         "partition": {
            "name": "issues"
         },
         "offset": {
            "date_updated": 1618184736
         }
         }
      ],
      "requested_at": "2024-03-28T17:58:45.606796307Z",
      "type": "PATCH"
   },
   "status": {
      "phase": "APPLIED",
      "message": "The Connect framework-managed offsets for this connector have been altered successfully. However, if this connector manages offsets externally, they will need to be manually altered in the system that the connector uses."
   },
   "previous_offsets": [
      {
         "partition": {
         "name": "issues"
         },
         "offset": {
         "date_updated": "2023-11-07 18:44"
         }
      }
   ],
   "applied_at": "2024-03-28T17:58:48.079141883Z"
}

Responses include the following information:

The original request, including the time it was made.
The status of the request: applied, pending, or failed.
The time you issued the status request.
The previous offsets. These are the offsets that the connector last updated prior to updating the offsets. Use these to try to restore the state of your connector if a patch update causes your connector to fail or to return a connector to its previous state after rolling back.

JSON payload¶

The table below offers a description of the unique fields in the JSON payload for managing offsets of the Jira Source connector.

Field	Definition	Required/Optional
`name`	The name of the table.	Required
`date_updated`	The Unix timestamp of the last update in the row of the target table.	Required

Quick Start¶

Use this quick start to get up and running with the Confluent Cloud Jira Source connector. The quick start provides the basics of selecting the connector and configuring it to get data from one or more Jira resources.

Prerequisites

Authorized access to a Confluent Cloud cluster on Amazon Web Services (AWS), Microsoft Azure (Azure), or Google Cloud.
The Confluent CLI installed and configured for the cluster. See Install the Confluent CLI.
Schema Registry must be enabled to use a Schema Registry-based format (for example, Avro, JSON_SR (JSON Schema), or Protobuf). For additional information, see Schema Registry Enabled Environments and Cloud connector limitations.
Authorization and credentials to access the Jira server.

Using the Confluent Cloud Console¶

Step 1: Launch your Confluent Cloud cluster¶

See the Quick Start for Confluent Cloud for installation instructions.

Step 2: Add a connector¶

In the left navigation menu, click Connectors. If you already have connectors in your cluster, click + Add connector.

Step 3: Select your connector¶

Click the Jira Source connector card.

Step 4: Enter the connector details¶

Note

Make sure you have all your prerequisites completed.
An asterisk ( * ) designates a required entry.

At the Add Jira Source Connector screen, complete the following:

Select the way you want to provide Kafka Cluster credentials. You can choose one of the following options:
- My account: This setting allows your connector to globally access everything that you have access to. With a user account, the connector uses an API key and secret to access the Kafka cluster. This option is not recommended for production.
- Service account: This setting limits the access for your connector by using a service account. This option is recommended for production.
- Use an existing API key: This setting allows you to specify an API key and a secret pair. You can use an existing pair or create a new one. This method is not recommended for production environments.
Click Continue.

Enter the following Jira server connection details:
- Jira URL: The Jira server URL. For example: https://<server-name>.atlassian.net.
- Jira Username: Username or email associated with the Jira account.
- Jira API key: API key for the Jira account.
Click Continue.

Enter the following configuration details:
- Topic Name Pattern: The pattern to use for the topic name where the ${resourceName} literal will be replaced with each resource name.
- Since: Records created or updated after this time will be processed by the connector. The expected format for jira.since is yyyy-MM-dd HH:mm.
- Jira resources: The resources that are to be extracted and written to Kafka.
Select the output record value format (data going to the Kafka topic): AVRO, JSON, JSON_SR (JSON Schema), or PROTOBUF. Schema Registry must be enabled to use a Schema Registry-based format (for example, Avro, JSON Schema, or Protobuf). For additional information, see Schema Registry Enabled Environments .

Note

For Schema Registry-based output formats, the connector attempts to deduce the schema based on the source API response returned. The connector registers a new schema for every NULL and NOT NULL value of an optional field in the API response. For this reason, the connector may register schema versions at a much higher rate than expected.
Show advanced configurations
- Schema context: Select a schema context to use for this connector, if using a schema-based data format. This property defaults to the Default context, which configures the connector to use the default schema set up for Schema Registry in your Confluent Cloud environment. A schema context allows you to use separate schemas (like schema sub-registries) tied to topics in different Kafka clusters that share the same Schema Registry environment. For example, if you select a non-default context, a Source connector uses only that schema context to register a schema and a Sink connector uses only that schema context to read from. For more information about setting up a schema context, see What are schema contexts and when should you use them?.
- Maximum Batch Size: Defaults to 100 records.
- Maximum In Flight requests: The maximum number of requests that may be in flight at one time. Defaults to 10 requests.
- Maximum Poll interval (ms): The time in milliseconds (ms) between requests to fetch changed or updated resources. Defaults to 3000 ms (3 seconds).
- Request Interval (ms): The time in milliseconds to wait before checking for updated records. Defaults to 15000 ms (15 seconds).
- Maximum Retries: The maximum number of times the connector retries a task before the task fails. Defaults to 10 retries.
- Retry Backoff (ms): The time in milliseconds to wait following an error before a retry attempt is made. Defaults to 3000 ms (3 seconds).
- Transforms and Predicates: For more information, see the Single Message Transforms (SMT).
For all property values and definitions, see Configuration Properties.
Click Continue.

Step 5: Check for records¶

Verify that records are being produced in the Kafka topic.

For more information and examples to use with the Confluent Cloud API for Connect, see the Confluent Cloud API for Managed and Custom Connectors section.

Using the Confluent CLI¶

To set up and run the connector using the Confluent CLI, complete the following steps.

Note

Make sure you have all your prerequisites completed.

Step 1: List the available connectors¶

Enter the following command to list available connectors:

confluent connect plugin list

Step 2: List the connector configuration properties¶

Enter the following command to show the connector configuration properties:

confluent connect plugin describe <connector-plugin-name>

The command output shows the required and optional configuration properties.

Step 3: Create the connector configuration file¶

Create a JSON file that contains the connector configuration properties. The following example shows the required connector properties.

{
  "connector.class": "JiraSource",
  "name": "JiraSourceConnector_0",
  "kafka.auth.mode": "SERVICE_ACCOUNT",
  "kafka.service.account.id": "<service-account-resource-ID>",
  "jira.url": "https://<server-name>.atlassian.net",
  "jira.username": "<authorized-user>",
  "jira.api.token": "*********************************",
  "jira.since": "2020-06-14 09:30",
  "jira.resources": "issues, users, worklogs",
  "output.data.format": "JSON",
  "tasks.max": "1",
}

Note the following property definitions:

"connector.class": Identifies the connector plugin name.
"name": Sets a name for your new connector.

"kafka.auth.mode": Identifies the connector authentication mode you want to use. There are two options: SERVICE_ACCOUNT or KAFKA_API_KEY (the default). To use an API key and secret, specify the configuration properties kafka.api.key and kafka.api.secret, as shown in the example configuration (above). To use a service account, specify the Resource ID in the property kafka.service.account.id=<service-account-resource-ID>. To list the available service account resource IDs, use the following command:
```
confluent iam service-account list
```
For example:
```
confluent iam service-account list

   Id     | Resource ID |       Name        |    Description
+---------+-------------+-------------------+-------------------
   123456 | sa-l1r23m   | sa-1              | Service account 1
   789101 | sa-l4d56p   | sa-2              | Service account 2
```
Enter the GitHub connection details.
"jira.url": The Jira server URL. For example: https://<server-name>.atlassian.net.
"jira.api.token": API key for the Jira account.
"jira.since": Records created or updated after this time will be processed by the connector. The expected format for this property is yyyy-MM-dd HH:mm. Note that the value should be configured according to the timezone set in the Jira environment for the jira.username configured.
"jira.resources": One or more resources that the connector extracts and writes to Kafka. See Jira Resources for details.
output.data.format": Enter an output data format (data going to the Kafka topic): AVRO, JSON_SR (JSON Schema), PROTOBUF, or JSON (schemaless). Schema Registry must be enabled to use a Schema Registry-based format (for example, Avro, JSON_SR (JSON Schema), or Protobuf). For additional information, see Schema Registry Enabled Environments and Cloud connector limitations.

Note

For Schema Registry-based output formats, the connector attempts to deduce the schema based on the source API response returned. The connector registers a new schema for every NULL and NOT NULL value of an optional field in the API response. For this reason, the connector may register schema versions at a much higher rate than expected.
"tasks.max": The connector supports running one or more tasks. More tasks may improve performance.

See Configuration Properties for all property values and descriptions.

Step 4: Load the properties file and create the connector¶

Enter the following command to load the configuration and start the connector:

confluent connect cluster create --config-file <file-name>.json

For example:

confluent connect cluster create --config-file jira-source-config.json

Example output:

Created connector JiraSourceConnector_0 lcc-do6vzd

Step 5: Check the connector status¶

Enter the following command to check the connector status:

confluent connect cluster list

Example output:

ID           |             Name            | Status  | Type   | Trace
+------------+-----------------------------+---------+--------+-------+
lcc-do6vzd   | JiraSourceConnector_0       | RUNNING | source |       |

Step 6: Check the Kafka topic.¶

Verify that records are being produced at the Kafka topic.

For more information and examples to use with the Confluent Cloud API for Connect, see the Confluent Cloud API for Managed and Custom Connectors section.
