Load External Data into a Dataset
External Data API Reference
EXTERNAL DATA
You can integrate external data into Analytics Cloud to make the data available for queries from explorer and designer
The External Data API enables you to upload external data files to Analytics Cloud The External Data API can upload csv files and you
can optionally specify the structure of your data by defining metadata in JSON format
The External Data API is available in API version and later
The highlevel steps for uploading external data by using the API are
Prepare your data in CSV format and then create a metadata file to specify the structure of the data
Connect programmatically to your Salesforce organization
Configure the upload by inserting a row into the InsightsExternalData object and then set input values such as the name of the
dataset the format of the data and the operation to perform on the data
Split your data into MB chunks and then upload the chunks to InsightsExternalDataPart objects
Start the upload by updating the Action field in the InsightsExternalData object
Monitor the InsightsExternalData object for status updates and then verify that the file upload was successful

External Data API Limits
When working with the External Data API consider the following limits in addition to the general Analytics Cloud limits
The following limits apply to all supported editions
Limit
Value
Maximum file size per external data upload
GB
Maximum file size for all external data uploads in a rolling hour GB
period
Maximum number of external data jobs per dataset that can be
run in a rolling hour period
Maximum number of characters in a field
Maximum number of fields in a record
including up to date fields
External Data
Prepare Data Files
Limit
Value
Maximum number of characters for all fields in a record
Prepare Data Files
To upload external data from csv files into a dataset first prepare your data files
External data can be loaded into a dataset by preparing two files
A data file which contains the external data in commaseparated value CSV format
An optional metadata json file which describes the structure of the data file
Note Providing a metadata file is recommended
The data and metadata files are used to populate a dataset with the external data For detailed information about formatting CSV data
and JSON metadata see the Analytics Cloud Extended Metadata XMD Reference
Connect to Salesforce
After preparing your data files the next step in loading external data into Tableau CRM is to connect to your Salesforce organization by
using standard Salesforce APIs
Note The following examples use the SOAP API but you can use any of the Salesforce APIs such as the REST API or Apex The
examples assume that youre using the Web Services Connector
To load external data into Tableau CRM first connect to your Salesforce organization Use the PartnerConnection object to log in to your
organization as shown in the following example Youll need to supply a username password and endpoint
ConnectorConfig config new ConnectorConfig
configsetUsernameusername
configsetPasswordpassword
configsetAuthEndpointendpoint
PartnerConnection partnerConnection new PartnerConnectionconfig
For more information about the Web Services Connector WSC see Introduction to the Web Services Connectoron the Salesforce
Developers website For more information about user authentication see Security and the API in the SOAP API Developers Guide
Configure the Upload
Configure the external data upload by inserting a row into the InsightsExternalData object and setting configuration values
After establishing a connection with Salesforce insert a row into the InsightsExternalData object to configure and control the upload
The InsightsExternalData object provides a header that contains information about the upload such as the name of the dataset the
format of the data and the operation to perform on the data You can also provide the metadata file The following example inserts a
row into the InsightsExternalData object and sets configuration values
SObject sobj new SObject
sobjsetTypeInsightsExternalData
sobjsetFieldFormatCsv
sobjsetFieldEdgemartAlias DatasetName
sobjsetFieldMetadataJsonmetadataJson

Note The WSC converts the metadata json file to a Baseencoded string but if youre using the REST API youll need to make
this conversion yourself
For detailed information about the InsightsExternalData object see InsightsExternalData
Add the Data
When uploading external data files you can use the InsightsExternalDataPart object to load the data in smaller chunks
After inserting a row into the InsightsExternalData header object split your data into MB chunks and upload the chunks to
InsightsExternalDataPart objects You associate the part objects with the header object by setting the InsightsExternalDataId
field on the part objects to the ID of the header object The part objects contain the bytes of data and must be assigned part numbers
in a contiguous sequence starting with
Ensure that the chunks of data are smaller than MB If the data is compressed it must be compressed first and then split into MB
chunks Only the gzip format is supported
The following example splits a file into MB chunks and then uploads the chunks to InsightsExternalDataPart objects
ListFile fileParts chunkBinarydataFile Split the file

For detailed information about the InsightsExternalDataPart object see InsightsExternalDataPart
Manage the Upload
After youve created a header and uploaded the data parts by using the InsightsExternalData and InsightsExternalDataPart
objects update the Action field on the header object to Process to start processing the data
The following example sets the Action field and updates the row in the InsightsExternalData object
SObject sobj new SObject
sobjsetTypeInsightsExternalData
sobjsetFieldActionProcess

sobjsetIdparentID This is the rowID from the previous example
SaveResult results partnerConnectionupdatenew SObject sobj
forSaveResult svresults
ifsvisSuccess
rowId svgetId
When the Action field is set to Process a dataflow job is created and marked active You can monitor the Status field of the
header object to determine when the file upload is completed After the Action field is updated to request processing no user edits
are allowed on the objects
External Data API Reference
The InsightsExternalData Object
The InsightsExternalData object enables you to configure and control external data uploads You can use it to provide metadata trigger
the start of the upload process check status and request cancelation and cleanup
The InsightsExternalData object is used with the InsightsExternalDataPart object which holds the parts of the data to be uploaded
Together they provide a programmatic way to upload a large file in parts and trigger a dataflow into a dataset The first step is to insert
a row into the InsightsExternalData object Data parts are then uploaded to InsightsExternalData objects The Action field of the
InsightsExternalData object is updated to start processing and request cancelations After the Action field is updated to request
processing no user edits are allowed on the objects except to request cancelation
Note The standard system fields CreatedById CreatedDate LastModifiedById LastModifiedDate and
SystemModstamp are documented in System Fields in the SOAP API Developers Guide
The InsightsExternalData object is available in API version and later
