Salesforce

This Gem has below features:

1. Dataset Creation - Create Dataset in Salesforce Wave from Spark DataFrame.
2. Read Salesforce Wave Dataset - User has to provide SAQL to read data from Salesforce Wave. The query result will be constructed as DataFrame.
3. Read Salesforce Object - User has to provide SOQL to read data from Salesforce object. The query result will be constructed as DataFrame.
4. Update Salesforce Object - Salesforce object will be updated with the details present in DataFrame.

note

This connector is built on top of the already available spark-salesforce connector

To use this Gem in Prophecy, com.springml:spark-salesforce_2.12:1.1.4 Maven external dependency needs to be installed on cluster. For installing dependencies from Prophecy UI. Please check dependency management docs

Credential Type	Credential Type: Databricks Secrets or Username & Password	True
Credentials	Databricks credential name , else username and password for the snowflake account	Required if Credential Type is Databricks Secrets
Username	Salesforce Wave Username. This user should have privilege to upload Datasets or execute SAQL or execute SOQL	Required if Credential Type is Username & Password
Password	Salesforce Wave Password. Please append security token along with password.For example, if a user’s password is mypassword, and the security token is XXXXXXXXXX, the user must provide mypasswordXXXXXXXXXX	Required if Credential Type is Username & Password
Login Url	(Optional) Salesforce Login URL. Default value https://login.salesforce.com	True
Read from source	Strategy to read data: SAQL or SOQL.	True
SAQL Query	(Optional) SAQL query to used to query Salesforce Wave. Mandatory for reading Salesforce Wave Dataset
SOQL Query	(Optional) SOQL query to used to query Salesforce Object. Mandatory for reading Salesforce Object like Opportunity
Version	(Optional) Salesforce API Version. Default 35.0
Infer Schema	(Optional) Infer schema from the query results. Sample rows will be taken to find the datatype
Date Format	(Optional) A string that indicates the format that follow java.text.SimpleDateFormat to use when reading timestamps. This applies to TimestampType. By default, it is null which means trying to parse timestamp by java.sql.Timestamp.valueOf()
Result Variable	(Optional) result variable used in SAQL query. To paginate SAQL queries this package will add the required offset and limit. For example, in this SAQL query q = load \"<Dataset_id>/<Dataset_version_id>\"; q = foreach q generate 'Name' as 'Name', 'Email' as 'Email'; q is the result variable
Page Size	(Optional) Page size for each query to be executed against Salesforce Wave. Default value is 2000. This option can only be used if resultVariable is set
