I read somewhere that IN queries are processed serially by the
datastore. GOOGers, what is a rough rule-of-thumb on the benefit of
using IN? For example, if the base RT latency for anything with the
datastore is Nms, then could guesstimate that using N for a list of 3
is not a huge latency win,

In the context dashboard, what precisely does 'errors' mean?
I see an error frequency in the dashboard that is much higher than
what I see in the logs.

indexing (although the online doc indicates some max length
differences).

I second that. I have cases where I'm building a structure of multiple

to do another put() to the same object later on. Eliminating the 2nd
put() of the same object in the flow would also allow me to wrap it in
a transaction.
as a delimiter-separated list of IDs, though - 1/2/3/4 - and
