memcached stores data in memory, it doesn't persist it, therefore if the server goes down the data is lost. memcached will also bump data from memory when other items are requested more often, and memory space gets low.
<br><br>there is simply no guarantee that when you put something into memcached that it will be there later.<br><br>Hope this helps,<br>Kevin<br><br><div><span class="gmail_quote">On 5/8/07, <b class="gmail_sendername">Dawei Wang

Hi,All:<br><br>I found that some people said that memcached sometimes will lose data. I really don't understand why this happens. can someone explain this?<br><br>yet I found a bug with it (C# client API) ,it key has space (for example "test 123" ), then it will fail to set to memcached. so I just remove space before set t omemcached, and now I used it as cache in our website, it seems fine to me...
