Re: Best memcached proxy to use

2010-07-06T15:14:31Z

BTW, I mean a connection proxy, not a web proxy using memcache as
storage. Something to reduce number of connections of the memcache
servers, and that can be used as multi-layer memcache infraestructure.

Data Size Issue

2010-04-12T08:03:03Z

Hi there,
We are running memcachedb 1.2.1 on a 4GB memory machine with "-m 1836"
option, and it accumulated over 11GB data when it started to get
slower and slower. By this time we have about 12m data items. We
didn't want to shut down the site to do the repartitioning, so we ran
some scripts to delete about 1/3 of the data. But the data file sizes

memcachedb performance at 50 million for random set operations terrible

2010-03-19T01:06:27Z

So I'm seeing some terrible performance once the size of my memcacheDB
gets to about 50 million records. I'm using a hash database backing in
the BDB.
my startup:
memcacheDB -m 10000 -b 4096 -N -A 4096 -B hash
my keys are pretty simple digits 1 to 50 million.

Expiration. Again.

2010-03-18T19:36:30Z

It seems bizarre to me that MemCacheDB still requires that a SET
command have an expiration parameter,
which it ignores.
I would like this to be a command-line switch (--enable-expiration).
Doing your own is a pain. What if you want client information to be
persisted for 4 days, but deleted after that. It would be great if

I was wondering if anyone had any good experience with such a use case?

support for binary UDP protocol

2010-02-20T17:17:14Z

Hi,
We currently use memcached with a binary udp protocol client and are
now evaluating the use of the memcachedb with the same client for a
different feature.
Does memcachedb support binary UDP protocol, as in memcached, or does
it support only tcp protocol ?
Thanks in advance,
Balaji.

memcachedb-client for Ruby

2010-02-14T23:30:51Z

Hello,
I created a memcachedb client for ruby. It is based on memcache-client
but adds the possibility of handling groups of master-slaves
automatically. So it will determine from a group of servers which one
was elected master and which are slaves. You can also use multiple
such group to have more then a single master if needed.

memcacheq: reclaim disk space

2010-01-15T01:34:37Z

Hello,
I've been using memcacheq and its been working great for the past few
months. In that time, it has accumulated a tremendous amount of disk
space. Is it possible to reclaim some of that disk space?
I am seeing a lot of log.xxxxx files in the memcacheq directory. Is it
safe to delete some of these files?

Hi,
I've got memcacheq working locally, but I'm having some issues with

from the queue. Is there a way I can delete an individual item from
the queue ?

It works quite good. But suddenly I start getting error "DB->put:

Deleting values - expiration with memcachedb

Thanks to Steve and the team at Northscale for all their memcached
contributions.

We are new to memcachedb. Looks like a promising product to keep our

Noticed in Steve's complete guide PDF the mention of *NO* expiration.
Want to be clear about what this means and get clarification from

Hi, all,

Long time since last release, anyway we got new release. This version

of queue instantly and know all pops and pushes that we have done.
This is very useful in production and make us take full control of our
application data flow. We design the stats carefully, and no

Hello,

Is it possible to set a maximum size for the berkeley db on disk (eg,

amount.

We're looking to use memcachedb and while setting it up, I had a
few questions.

memcache.py that I can't find in it. I have the newest non-beta
version of memcache (1.2.0) and while it does have two of the new
functions, 'rep_set_ack_policy', 'rep_set_priority', it doesn't have

Memcacheq db size keeps on growing

2009-11-04T16:30:52Z

Hi,

I have been experimenting with the memcacheq and although we are
putting and getting all the items the database size on disc is
continually growing - i.e. when we pop all the records they remain in
the database. So preiodically I have to stop the queue and delete the
queue/database - otherwise I run out of disc space.
