My app serves a fair amount of requests about 4 a second and ruffly half of them save to the datastore. It is very fault tolerant so our users shouldn't be noticing it - and if they are it's still fairly minor. In the last 9 hours we have had 10% of these requests fail (about 13,700 requests). Prior to 2 days ago it was not uncommon to see the failure rate around 1% less than 100 failures for over 20 hours. The code that saves to the data store saves a model that has a reference to another object. This referenced object is pretty simple - StringProperty objects and a couple DateProperty objects.
Is saving this reference more expensive than creating a uniqueId of the (simple)object and manually saving a the custom defined uniqueId to it? If this continues throughout the day I guess I'll turn profiling back on and see what's going on... Any thoughts on re-working the reference? Is it a more expensive operation to save and retrieve references to objects rather than a custom unqique key to the object? If I reworked the relationship it would force me to turn back around and query to get the referenced object when I need it though. Thanks for helping! -Aaron On Sat, Jan 3, 2009 at 2:56 AM, Paul Kinlan <[email protected]> wrote: > Hi, > > I also regularly get datastore timeouts for reads and writes.
