After initial testing, I already love transactions, started generating some gotchas of my own, going to share them when I finish testing/modifications (for newbies to transactions like me)
Before going deeper into transactions, I want to ask some questions: - Is there a downside of using transactions cost/performance wise? ( retries=10 should potentially 10x increase the cost/performance, but is there anything other than that, something like "transactional costs are reflected as 3x to appengine costs"(made up) etc. -- or any overhead other than retries ) - Is there any downside of using xg=True ? Also something like a "dominant transaction" would have been great For example a pipeline routine could be computing 500 operations at once, but a small transaction might take priority and cause the re-computation of 500 tasks, increasing computation costs / slowing down the pipeline etc. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
