Which leads to a potential constructive suggestion. Maybe Goog can
post a troubleshooting guide that lists different line-items in the
new-style billing, and potential gotchas? An example in your blog is
that sudden parallelism is costly and that making things serial is a
good optimization. (Ironically, the opposite of what was being
promoted earlier - mapreduce). Another factoid is that offset queries
are costly. Using queries as a generator is costly, and you should
fetch items at once.
So it can look like this:
Excessive instances cost? Look at these items:
- sudden parallelism
- idle instance setting
- decrease response time
- decrease unneeded indexes
- make sure your fetch() rather than looping through results
- check offset queries
