Salesforce Bulk API 2.0 Source Connector for Confluent Cloud

The fully-managed Salesforce Bulk API 2.0 Source connector for Confluent Cloud integrates Salesforce.com with Apache Kafka®. This connector pulls records and captures changes from Salesforce.com using Salesforce Bulk API 2.0.

Note

This is a Quick Start for the fully-managed cloud connector that uses Salesforce Bulk API 2.0. If you are installing the fully-managed cloud connector that supports the original Salesforce Bulk Query API, see Salesforce Bulk API Source Connector for Confluent Cloud.

Features

The Salesforce Bulk API 2.0 Source connector provides the following features:

  • API 2.0: Supports Salesforce Bulk API 2.0.
  • At least once delivery: The connector guarantees that records are delivered at least once to the Kafka topic. If the connector restarts, there could be duplicate records in the Kafka topic.
  • Supported data formats: The connector supports Avro, JSON Schema, Protobuf, or JSON (schemaless) output data. Schema Registry must be enabled to use a Schema Registry-based format (for example, Avro, JSON_SR (JSON Schema), or Protobuf). See Schema Registry Enabled Environments for additional information.
  • Tasks per connector: Organizations can run multiple connectors with a limit of one task per connector (that is, "tasks.max": "1").
  • 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.

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:

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": {
          "table": "Account"
        },
        "offset": {
          "jobId": "7505i00000Ug2TKAAZ",
          "locator": "null",
          "time": "2024-04-09T15:32:45Z"
        }
      }
    ],
    "metadata": {
        "observed_at": "2024-03-28T17:57:48.139635200Z"
    }
}

Responses include the following information:

  • jobId, locator, and time indicate the position of the 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.

JSON payload

The table below offers a description of the unique fields in the JSON payload for managing offsets of the Salesforce Bulk API 2.0 Source connector.

Field Definition Required/Optional
time

Represents the time of the last query to bulk API. When you reset the offset, the connector selects events with a time greater than and equal to the specified value in time. To update offsets, it is recommended that you only use a value in time and two double quotes ("") for jobID and locater.

Use the following format for time: yyyy-MM-dd'T'hh:mm:ss'Z'

 Required
jobId Unique ID for the bulk v2 query job. This field is not available in kafka records. Optional
locator Pointer to the next batch of records. This field is not available in kafka records. Optional

Quick Start

Use this quick start to get up and running with the Salesforce Bulk API 2.0 Source connector. The quick start provides the basics of selecting the connector and configuring it to capture records and record changes from Salesforce.
