But not for every situation... </p> <ul> <li>You have objects larger than 1MB. <ul> <li>Memcached is not for large media and streaming huge blobs. </li> <li>Consider other solutions like: <a href="http://www.danga.com/mogilefs" rel="nofollow noreferrer">http://www.danga.com/mogilefs</a> </li> </ul></li> <li>You have keys larger than 250 chars. <ul> <li>If so, perhaps you're doing something wrong? </li> <li>And, see this mailing list conversation on <a href="http://lists.danga.com/pipermail/memcached/2007-January/003388.html" rel="nofollow noreferrer">key size</a> for suggestions. </li> </ul></li> <li>Your hosting provider won't let you run memcached. <ul> <li>If you're on a low-end virtual private server (a slice of a machine), virtualization tech like vmware or xen might not be a great place to run memcached. Memcached really wants to take over and control a hunk of memory -- if that memory gets swapped out by the OS or hypervisor, performance goes away. Using virtualization, though, just to ease deployment across dedicated boxes is fine. </li> </ul></li> <li>You're running in an insecure environment. <ul> <li>Remember, anyone can just telnet to any memcached server. If you're on a shared system, watch out! </li> </ul></li> <li>You want persistence. Or, a database. <ul> <li>If you really just wish that memcached had a SQL interface, then you probably need to rethink your understanding of caching and memcached. </li> </ul></li> </ul>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
