I thought the cloud was infinite? How disappointing, that there are limits. Next you will tell me that the All you can eat pancakes at the iHop doesn't allow me to just live in a booth there and eat forever on $5.99 From: [email protected] [mailto:[email protected]] On Behalf Of Ikai Lan (Google) Sent: Friday, November 04, 2011 5:52 PM To: [email protected] Subject: Re: [google-appengine] Re: do backends and frontends share memcache? No, you can't really lock a Memcache key. There's probably an application bug somewhere. Memcache should be strongly consistent, so any read that happens after the write should return the last written data. I would try writing it from one instance and reading it from the same instance. Something else might be going on. Like all computer systems, there is probably *some* upper bound to Memcache's write throughput on a single value, but it should be way, way higher than 50 a second. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com <http://plus.ikailan.com/> | twitter.com/ikai On Fri, Nov 4, 2011 at 5:45 PM, Andrius A <[email protected]> wrote: What if one memcache entity is updated at the high rate (maybe 50 times per second) could that lock it so other backends/frontends cant read it?
