The datastore latency graph is still broken (URI too long for Google Charts):
http://code.google.com/status/appengine/detail/datastore/2010/03/10#ae-trust-detail-datastore-query-latency In the periods when it works, it reports query latencies sometimes over one second. The graph is usually accompanied by "We have determined that this spike did not affect the performance or uptime of applications." Really? One-second query latencies do not "affect the performance ... of applications"? Is it the case that query latencies which routinely exceed one second are considered "normal?" What is the difference between query latency and get/put/delete latency? Does a database look-up involve both? Meaning: if there is a 400ms delete latency and a 900ms query latency, will my users have to wait 1.3 seconds for a database call which causes a delete? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
