<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">memcachedb is designed for high-frequency writing and reading, when<br>your data structure is simple but with a high writing load, usually
<br>when your writing load is equal to reading, it works.<br>So it is good for site counter(that usually slows the whole mysql) and<br>index servers, also any high writing and reading situation.<br><br>Now memcachedb is working for our high-traffic site countering service
<br>with a writing load of 1500+ per second per daemon, and with a<br>moderate load of CPU. The response time is less than 50ms when we give<br>it a apache module httpd frontend.<br><br>Google Account is good example to using Berkeley DB, though without
<br>using memcache front end. Memcachedb has the same architecture goal<br>with it.<br>See: <a href="http://www.usenix.org/events/worlds06/tech/prelim_papers/perl/perl.pdf">http://www.usenix.org/events/worlds06/tech/prelim_papers/perl/perl.pdf

<div>So does Memcachedb ever write the data back to say a MySQL db, or it by itself is the db?</div>
