Can you clarify in what way they are different?
A document should not be modified once it has been written to the output view. Making a copy of the document avoids issues. Change the loop to create a new wrapper Map
for item in sourceTables:
wrapper = java.util.HashMap(in_doc)
wrapper['query'] = "update iods_staging.{} set record_inserted = true;".format(item)
self.output.write(wrapper)
Hi Akidave,
Thanks you so much for your solution. However, I would really appreciate if you could explain me more why we should not modify the document once it has been written to the output view.
Thanks again.
Aditya
If a snap writes a document to output view and then modifies the document, the downstream snap might pick up the updated document value, not the document originally written. For performance reasons, a deep copy is not done automatically when the document is written to the output view.
Creating a Map in the script works in this case since the Script is changing only the top level keys. If the Script was changing the contents of the nested map, then a deep copy would be required in the Script
Thank you so much Akidave
