Issue 381 in memcached: Incomplete command does not result in ERROR response

2014-10-21 Thread memcached

Status: New
Owner: 
Labels: Type-Defect Priority-Medium

New issue 381 by tgrab...@cloudius-systems.com: Incomplete command does not  
result in ERROR response

https://code.google.com/p/memcached/issues/detail?id=381

What steps will reproduce the problem?

1. echo -n get key | nc -C localhost 11211

What is the expected output? What do you see instead?

I'd expect the server to reply with CLIENT_ERROR or ERROR, depending on  
the parsing state. However the server currently does not send any reply.


What version of the product are you using? On what operating system?

1.4.20

Max number of concurrent updates for a same key at same time in memcache.

2014-10-21 Thread Shashank Sharma
Hi all,

Reading memcache documents its clear that it can handle a very heavy load 
of traffic. However I was more interested in knowing the bound on how may 
updates for a specific key at the same time can memcache handle.

Re: Max number of concurrent updates for a same key at same time in memcache.

2014-10-21 Thread dormando
Internally, there's a per-item lock, so an item can only be updated by one
thread at a time.

This is *just* during the internal update, not while a client is uploading
or downloading data to the key. You can probably do several thousand
updates per second to the same key without problem (like incr'ing in a
loop). Possibly a lot more (100k+)

What're you trying to do which requires updating one key so much?
