Then also upgrade your OS to Squeeze (latest stable) :)

I was actually going to ask if this was a draft of a changelog going on

I understand why the 'official' protocol.txt is where it is, but to get

I get why you may strike out on your own and write an extension to memcached
that does exactly what you want (kind of, there _are_ better tools, as
mentioned),
that's precisely what open source is about. I do not get why you're so

that just fizzle due to other priorities (e.g. releasing membase)?

There's no actual 'housecleaning' per se, just lazy expiration and
eviction. If an item's expiration time is reached, the next time its
key is requested, the lookup fails. If the server is out of memory,
it'll evict expired items first, but if nothing's expired, will start
evicting things in a leas
Hah! We're currently using the BeIT client, and were wondering if
there was a timeline for binary protocol and NorthScale support,
actually.

Part of the disconnect is that, "how do I have to run memcached to
'store' these sessions in memcached," is not a concrete question. It's
wibbly wobbly at best to try and achieve this behavior, and, "You
can't," _is_ concrete in that there is no way to do this in a
mathematically provable way. The

Now you have two problems.

If the scale is actually only hundreds per minute, even sequentially,
I wouldn't worry about memcached writes being the bottleneck, even on
a small machine.

And are you using persistent connections? There have been a handful of

Hi All,
We've been testing a write-heavy scenario (hence the get/set
discrepancy) using the Jellycan build of 1.2.6 on Windows Server 2003.
There's a staging server throwing live data at the memcached server
(items are roughly 2-300 bytes apiece), and are seeing the number of
curr_items stagnate
We've got a couple of small-but-high-throughput installations running on
Win2k3 servers with little issue, are there any particular problems you're
seeing? Are both the servers and clients on Win2k3, and are the errors
client errors or server errors? What versions are you using, etc. ?
Best,
- Mar
The key is run through a hash function (client lib-depending), and
it's sent to the server whose list index is that value
mod(num_servers). It's not _perfectly_ spreading load, but on the
order which most memcached installations run, it's close enough.

Searching "memcached in:spam" yields only emails I've already flagged (and

PECL extensions are C-based, unlike PEAR extensions, but you're right that
the PECL memcached client is basically a PHP wrapper over libmemcached,
while PECL's memcache client is hand-rolled. I don't keep track of issues
with either client, but the 'beta' designation wouldn't hold me back from

We definitely saw this exact same behavior with the PHP PECL module, using
consistent
hashing. Weirdly enough, I was just digging around before responding, and
version 3.0.4 was released a few days ago with the changelog statement:
"Improved performance of consistent hash strategy." You might check
Henrik is completely right about your idea being beyond the scope of what
memcached is, but what you might want to look at is something like a
