I am using pipeline/MR api to perform data queries and trying to understand whether the tasks generated by pipeline/MR api are idempotent or not. I think they are not, which means there are chances when some task is executed more than once, the data queries results can be incorrect.
So if we need to guarantee results are correct, we need to run the same job odd times, like 3. And choose the results from the majority. Is this thought correct? Or any thoughts on this? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
