Datastore errors due to the above reasons are highly clustered: when a tablet is being moved, split, or merged, it's generally unavailable for anywhere from a few hundred milliseconds to a So that is a possible workaround until someone is able to reproduce it / fix it. The most common way this limitation gets encountered is when you update an entity with every request—for example, counting the number of views to a page on your site. this page Or are these types of HTTP 500 errors not logged at all?

This article will explain why errors occur, and what you can do when they do, in order to minimize disruption to your users. My API was working perfectly and suddenly, during a period of time of around an hour we started to get these kind of errors.

Bigtable is fairly smart about splitting hot tablets to spread the load, but if all the updates are for a single row, or are consecutive, this isn't enough to relieve the Timeouts due to write contention The first type of timeout occurs when you attempt to write to a single entity group too quickly. This request, and this task, run successfully most of the time. With the introduction of the Task Queue, another option is to create a task queue item to do the update later; this allows you to make it past high traffic periods
