Does a crash on the development server result in wiping out the datastore?

While testing my app on the development server, I've noticed that manually interrupting a request sometimes results in clearing the datastore. This includes models that were not even modified by the interrupted request, such as users, etc.

Any thoughts on why this might be happening? Thank you

Answer №1

To enhance your SDK experience, I highly suggest switching to the SQLite stub instead of the default file-based stub. You can learn more about this in this informative blog post written by Nick Johnson, the creator of the stub. Simply add the flag --use_sqlite=true when running dev_appserver.py to enjoy all the benefits of SQLite, including a feature that prevents datastore wiping during crashes.

Answer №2

The development data store in GAE is essentially a local simulation of the production data store, mimicking BigTable on your disk. If operations are interrupted abruptly, there is a risk of data inconsistency.

To mitigate this concern, it's advisable to regularly backup your local data store so you can restore it in case of any unforeseen issues.
