/*
bulk command
force bulk insert mydata.csv
The load process involves these steps
1. Create a job
https://instance_name—api.salesforce.com/services/async/APIversion/job
payload:
<jobInfo xmlns="http://www.force.com/2009/06/asyncapi/dataload">
<operation>insert</operation>
<object>Account</object>
<contentType>CSV</contentType>
</jobInfo>
2. Add batches to the created job
https://instance_name—api.salesforce.com/services/async/APIversion/job/jobid/batch
payload:
<sObjects xmlns="http://www.force.com/2009/06/asyncapi/dataload">
<sObject>
<description>Created from Bulk API on Tue Apr 14 11:15:59 PDT 2009</description>
<name>[Bulk API] Account 0 (batch 0)</name>
</sObject>
<sObject>
<description>Created from Bulk API on Tue Apr 14 11:15:59 PDT 2009</description>
<name>[Bulk API] Account 1 (batch 0)</name>
</sObject>
</sObjects>
3. Close job (I assume this submits the job???)
https://instance_name—api.salesforce.com/services/async/APIversion/job/jobId
payload:
<jobInfo xmlns="http://www.force.com/2009/06/asyncapi/dataload">
<state>Closed</state>
</jobInfo>
Jobs and batches can be monitored.
