Hi Tim,
Thanks for the thoughtful response. You're right that some of this "bugs" refer just to sqlite related issues, and some indeed highlight problems in the default file based datastore stub, not in sqlite. The 2 most concerning seem to be the one about inequality filters and the requiring indexing but hey, I can deal with those. Also, appropriately, there a lot of things that only occur in the production datastore such as transaction retries, deadline exceeded, etc. Even non related stuff that I should prepare for such as capabilities disabled, etc, etc. I wish I had better coverage of my code with unit testing to find also regressions, etc, etc. Sadly, I don't. My app is pretty modest, amateurish, at best. http://www.askaro.com Now, sadly, now that I've switched to sqlite, still observing, via app stats, that queries are taking 3 seconds. I was hoping for a real boost. There might be something off with my environment (python 2.5) but I can't see what that could be. I guess I could profile the sqlite stub to find out but I'd like to know if when people mean fast they mean queries that take 3 seconds. I was just casually perusing the structure of indexes. Looks like filtering, sorting, etc is done in memory (see below). Anyhow, I'm less than 20K entities of my test and not crazy about the performance. sqlite> .schema CREATE INDEX "{my-app-id}!!EntitiesByKind" ON "{my-app-id}!!Entities" ( kind ASC, __path__ ASC); CREATE INDEX "{my-app-id}!!EntitiesByPropertyDesc" ON "{my-app-id}!!EntitiesByProperty" ( kind ASC, name ASC, value DESC, __path__ ASC); CREATE INDEX "{my-app-id}!!EntitiesByPropertyKey" ON "{my-app-id}!!EntitiesByProperty" ( __path__ ASC); -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
