Hello, We are at the planning phase on a new App Engine project, and we are unsure about the choice of Master/Slave and High Replication.
About our site: The site is expected to get a lot of hit (Around 50-200 QPS.). Around 20% write and 80% read. Minimal outrage a must. Will lose a lot of clients if outrages are too frequent. We would love to hear from fellow App Engine developers of their experiences with HR. In particular we want to know: 1) Recently the M/S datastore has very high latency for query. How’s your experience in HR? 2) What’s your approximate of the HR datastore availability? Is it close to 99.9%? 3) How is the read/write performance of HR datastore? Would love it if you could share some statistics. 4) How much does the cross datacenter synchronization issue affect the performance of your site? Please see this link about the issue: http://groups.google.com/group/google-appengine/browse_thread/thread/5fc3b6a4366de62f/4b4d23e924b7b136 It would be great if you could share your experience with us and other App Engine developers. Thank you very much. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
