Is tSalesforceOutput thread safe?

Anonymous — Sat, 16 Nov 2024 05:47:13 GMT

I am trying to streamline the loading of ContentVersion records (attachments) to salesforce by using a tFlowtoIterate with enable parallel execution to parallelize a call to a child job. I have also tried this without a child job and got the same result.

ContentVersions have to be loaded serially into salesforce, they can't be grouped in to batches greater than 1 record owing to various restrictions in salesforce.

So I am trying to work around this by setting up many threads all running a single record into salesforce.

To start with the job runs very fast with multiple threads executing to load into salesforce. However after n records the tSalesforceOutput component fails with the following string index error.

This error does not occur if I set the tRunJob to use separate processes for each execution however the overhead of setting up a new process for each iteration slows the process down so much it is no faster than the serial method.

So I suspect that something in tSalesforceOutput is not thread safe.

Has anyone seen this behaviour before or know if my hunch is correct?
