    Short Description

    SalesforceBulkReader reads records from Salesforce using Bulk API.

    Which Salesforce reader?

    If you need to read a small number of records, read attachments or use subqueries, use SalesforceReader.

    If you need to read a large number of records, use SalesforceBulkReader.

    SalesforceBulkReader Attributes

    Attribute Req Description Possible values

    Basic

    Connection

    yes

    A Salesforce connection. See Salesforce Connections.

    e.g. MySFConnection

    SOQL query

    yes

    A query for retrieving data from Salesforce.

    The component allows you to use subset of the SOQL language. It is the constraint of the Bulk API.

    If you query the records, you should use API names for objects and fields. The API name can differ from the name of an object in Salesforce web GUI.

    You can use graph parameters in a SOQL query.

    e.g. SELECT Name, Website FROM Account WHERE Industry = 'Energy'

    Output mapping

    Mapping from query fields to output metadata fields.

    Map by name (default)

    Advanced

    Read mode

    Enables or disables reading deleted or archived reports. You can choose between Do not return deleted or archived records (default) and Return also deleted or archived records.

    This attribute is available since 4.6.0-M2.

    Result polling interval (seconds)

    Time between queries for results of asynchronous calls.

    The default value is taken from the connection configuration.

    5 (default)

    Details

    SalesforceBulkReader reads records from Salesforce using Bulk API. Bulk API performs the operations asynchronously. It sends a request to Salesforce, waits several seconds and queries Salesforce for a result. The time interval is configured with the Result polling interval attribute. A shorter interval leads to quicker results, but consumes more of your Salesforce requests.

    To use the component, create a Salesforce connection, enter an SOQL query, and specify the output mapping. If you perform the steps in this order, the transform editor can provide you with metadata extracted from the SOQL query. Therefore, you will be able to map the fields with drag and drop.

    SOQL

    SalesforceBulkReader uses Salesforce Object Query Language (SOQL) to query data in Salesforce. However, only a subset of the language is supported by the Bulk API. Because of that, following parts of SOQL are not supported by SalesforceBulkReader:

    • COUNT

    • ROLLUP

    • SUM

    • GROUP BY

    • OFFSET

    • Nested queries

    • Relationship fields

    Order of Output Records

    The output records come out in arbitrary order unless you use ORDER BY in your query.

    SOAP or Bulk API

    If you read more than 10-15,000 records, it is better to use Bulk API because it will use less API requests.

    Notes and Limitations
    Address and Geolocation Compound Fields

    Bulk API does not allow you to read compound fields, e.g. address compound fields. See Compound Fields

    Attachments

    Bulk API does not allow you to read base64 fields. Therefore, attachments cannot be read using SalesforceBulkReader.

    API Requests

    SalesforceBulkReader uses multiple API calls during its run. All of them count towards your Salesforce API request limit. The precise call flow is:

    1. Login

    2. Extract fields of an expected result set from Salesforce object.

    3. Create a bulk query job.

    4. Create a batch with SOQL query.

    5. Get job completion status. This call is repeated in an interval specified by the Result polling interval attribute until the job is completed.

    6. Download a list of results sets.

    7. Download query results. The number of calls depends on the size of returned data. Salesforce limits the size of a single query result to 1GB.

    8. Close the bulk query job.

    Error messages

    When working with SalesforceBulkReader, you can hit the limitations of the Bulk API. The following error messages should help you identify the problem.

    FUNCTIONALITY_NOT_ENABLED: Selecting compound data not supported in Bulk Query

    The SOQL query asks for a compound data field (e.g. address), but this operation is not supported by the Bulk API. Query the particular fields of the compound field instead.

    Examples

    Reading records from Salesforce

    Reading addresses

    Reading object IDs

    Reading records from Salesforce

    This example shows the basic use case of SalesforceBulkReader.

    Read Account name, Industry and Website fields from Account.

    Solution

    Create a Salesforce connection.

    In SalesforceBulkReader, set up the Connection, SOQL Query and Output mapping attributes.

    Attribute Value

    Connection

    Connection from the first step

    SOQL query

    SELECT Name, Industry, Website FROM Account

    Output mapping

    See the code below

    //#CTL2
    
    function integer transform() {
        $out.0.Name = $in.0.Name;
        $out.0.Industry = $in.0.Industry;
        $out.0.Website = $in.0.Website;
    
        return ALL;
    }

    You can use output mapping if you have specified the SOQL query attribute.

    Creating a metadata with SalesforceBulkReader

    Connect an edge to the output port. In Output mapping, select the fields in the left side and drag them to the right side.

    Reading addresses

    This example shows a way to read addresses.

    Read the names and shipping addresses (street, city, state/province, postal code, and country) of customers from energy industry.

    Solution

    Create a Salesforce connection.

    In SalesforceBulkReader, fill in the Connection, SOQL Query and Output mapping attributes.

    Attribute Value

    Connection

    Connection from the first step

    SOQL query

    SELECT Name, ShippingStreet, ShippingCity, ShippingPostalcode, ShippingState, ShippingCountry FROM Account WHERE Industry = 'Energy'

    Output mapping

    See the code below

    //#CTL2
    
    function integer transform() {
        $out.0.Name = $in.0.Name;
        $out.0.ShippingStreet = $in.0.ShippingStreet;
        $out.0.ShippingCity = $in.0.ShippingCity;
        $out.0.ShippingPostalCode = $in.0.ShippingPostalCode;
        $out.0.ShippingState = $in.0.ShippingState;
        $out.0.ShippingCountry = $in.0.ShippingCountry;
    
        return ALL;
    }
    Reading object IDs

    This example shows reading object IDs from Salesforce.

    Read product names and object IDs of our Animal product family.

    Solution

    Create a Salesforce connection.

    In SalesforceBulkReader, set Connection, SOQL query and Output mapping.

    Attribute Value

    Connection

    Connection from the first step

    SOQL query

    SELECT Id, Name FROM Product2 WHERE Family = 'Animal'

    Output mapping

    See the code below

    //#CTL2
    
    function integer transform() {
        $out.0.Id = $in.0.Id;
        $out.0.Name = $in.0.Name;
    
        return ALL;
    }
