Python/Google app engine data storage performance | 5,395,833 | 5 | 1 | 496 | 0 | python,performance,json,google-app-engine,google-cloud-datastore | If your data is small, static and infrequently changed, you'll get the best performance by just writing your data as a dict in it's own module and just import it where you need it. This would take advantage of the fact that Python will cache your modules on import. | 0 | 1 | 0 | 0 | 2011-03-22T18:03:00.000 | 3 | 1.2 | true | 5,395,782 | 0 | 0 | 1 | 2 | In a python/google app engine app, I've got a choice between storing some static data (couple KB in size) in a local json/xml file or putting it into the datastore and querying it from there.

Overcoming 1mb file restriction in GAE Datastore | 5,413,209 | 0 | 2 | 349 | 0 | python,google-app-engine,google-cloud-datastore | You could work around this by splitting the blob into multiple pieces and storing them in separate entities. What you should do, though, is use the Blobstore as @Thilo suggests. | 0 | 1 | 0 | 0 | 2011-03-23T05:03:00.000 | 2 | 0 | false | 5,401,070 | 0 | 0 | 1 | 1 | As if for now, we are using datastore blob to store profile images of our site. And there is restriction in Datastore for storing more than 1mb file as a blob in datastore. Is there any work around for this. |
