[teiid-issues] [JBoss JIRA] (TEIID-4284) Implement Salesforce Bulk API for SELECTS to Salesforce Connector

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13312945#comment-13312945 ] 

Steven Hawkins commented on TEIID-4284:
---------------------------------------

One of the batches beyond the first is reporting its state as Failed or NotProcessed to produce that exception.  From the docs/examples I have an assumption that the first batch in the batchinfo list will be the initiating job batch.  If that is not a valid assumption I can adjust the code.  We should be able to confirm this if you run at a trace level.  Then there will be a log of the batchInfoList - https://github.com/teiid/teiid/blob/5210b0c40e2b8e4d5f1a8b888fa9b6d8608b1f1a/connectors/connector-salesforce/src/main/java/org/teiid/resource/adapter/salesforce/SalesforceConnectionImpl.java#L563

Otherwise this exception should mean that Salesforce has rejected the work in some way.

> There is some huge data (many GBs) in the Salesforce which has around 1.5 million rows and doing some simple select * on it fails with QUERY_TIMEOUT.  
> The salesforce guys suggested to try Bulk API for select with PK chunking as stated in https://developer.salesforce.com/docs/atlas.en-us.api_asynch.meta/api_asynch/asynch_api_code_curl_walkthrough_pk_chunking.htm .
