# Here `upsert=True` helps to insert a new doc into collection if there is no match on `{"name": x['name']}`,
# If there is a match doc will be updated, You can use `$set` or any-other operator depends on your use case.
for x in inputArray:
bulkArr.append(

# Opt for below - if you want to proceed on all dictionaries to be updated, even though an error occured in between for one dict
# result = db.collection.bulk_write(bulkArr, ordered=False)
print(result.bulk_api_result)
except:
e = sys.exc_info()[0]
print("An exception occurred ::", e) ## Get the ids failed if any & do re-try
