Your first paragraph should give you the answer.
why aren't you storing your tiles as entities in the store rather than
as files?

OK, thanks Brian. Final question - any pointers for reading from zip
files on the fly?

I was concerned about CPU quotas - each tile request would hit the
datastore.

1) put them in the datastore and memcache the mostly commonly used
(like the tiles at the startup level)
2) set client side cache headers for the tiles if they don't change
often
3) use alternative storage like Amazon S3

Hi Brian,
personally, i would not try the datastore method first. I have not
seen an issue yet with storing tiles as blobs
do you mean you *would* try the datastore method first? How many tiles
are you typically storing in the datastore?

See the standard Python zipfile module.

Variables won't. Constants aren't.
whoops, little typo: I would not try should be I would try.
there's no limit on the number of blobs you can store but you will hit
the storage quota in the preview. I have thousands in there right now
for testing purposes
It might be cheaper to store them on Amazon S3 but I have not worked
out
Thanks all, the verdict then is to try the datastore first. The tiles
will be refreshed on a regular basis (probably every 24 hours) using
an application outside the GAE, so the reliability and speed of the
bulk uploader will be an important factor. The last time I tried the
bulk uploader I found
