Can google datastore manage lots of continous write operations?

Can google datastore manage lots of continous write operations?

I'm using google app engine to read data from a google cloud sql database
and write some of its data and some derived data in google datastore, the
database right now doesn't have lots of entries per day, but it's
estimated to have around 200-300 entries per day on the future. I'm
testing to write all the data from the whole databse that now has a number
aproximately equal to these entries in it doesn't work properly, first of
all not all entries are being taken and derived data is sometimes properly
written and other times not, the result changes everytime I do a reading
from the database, so I guess that at least partially google datastore has
something that is related to the problem.
Don't know if google datastore could fall into race conditions or
something like that, although it would be sort of strange, but I'd like to
know if someone has had problems similar to mine and if how he was able to
solve it if he could.
Thanks.
