For that we have created summary tables, to ease searching. The problem we are seeing more and more are full table locks. We are moving to the XtraDB storage engine.
We use Memcached heavily. We have 45 GB of cache over 51 nodes. Most of the queries by primary key that we have to the users table are cached in Memcached and then delivered from there.
We have a system that lets automatically invalidate the cache every time one record of that table is modified.
With those databases we can update the cache with enough granularity to not need to invalidate it. Since mid we introduced RabbitMQ into our stack.
It's been a solution that was easy to deploy and integrate with our system. During the last month we have been moving more and more stuff to the queue, meaning that at the moment the 28 PHP frontend machines are publishing around We send logs, email notifications, system messages, image uploads, and much more to the queue.
This allows us to send messages to the queue in an asynchronous fashion. At the same time, all the messages that where hold in an array in memory are then sent to RabbitMQ.
In this way the user doesn't have to wait for this either. We have two machines dedicated to consume those messages, running at the moment 40 PHP processes in total to consume the jobs.
Each PHP process consumes jobs and then dies and respawns again. We do that to avoid any kind of garbage collection problems with PHP. In the future we may increase the number of jobs consumed per session in order to improve the performance, since respawing a PHP process proved to be quite CPU intensive.
This system lets us improve the resource management. For example during peak time we can even have logins per minute. This means that we will have concurrent updates to the users table, to store the user last login time.
Because now we enqueue those queries, we can run each of them sequentially instead. If we need more processing speed we can add more consumers to the queue, even joining machines to the cluster, without the need of modifying any configuration or deploying any new code.
To store the logs we run CouchDB in one machine. It proved to be useful to detect where the problem is. Before having CouchDB as a log aggregator, we had to login and tail -f in each of the PHP machines and from there try to find where the problem was.
Now we relay all the logs to the queue, and then a consumer inserts them into CouchDB. In this way we can check for problems at a centralized place.
We use Graphite to collect real time information and statistics from the website. The Graphite server is getting around update operations per minute.
This tool has proven to be really useful to see what's going on in the site. It's simple text protocol and the graphing capabilities make it easy to use and nearly plug and play to any system that we want to monitor.
One cool thing that we did with Graphite was monitoring two versions of the site running at the same time. Last January we deployed our code backed by a new version of the symfony framework.
This meant that we will probably encounter performance regressions. We were able to run one version of the site in half of the servers while the new version was running in the others.
Then in Graphite we created Unix load graphs for each half and then compared them live. Since we found that the Unix load of the new version was higher, we launched the XHProf profiler and compared both versions.
We have a separate server where we send the XHProf profiles and from there we aggregate them and analyze them to find where the problems are.
Our site also serves video to the users. We have two kinds of them. One are videos from the user profiles which are movies produced and uploaded by the users.
Also we have a Video Chat to let our users interact and share their videos. On mid we were streaming 17TB of video per month to our users.
Tsung is a distributed benchmarking tool written in Erlang. We have a tool to record traffic to the main MySQL server and convert that traffic to Tsung benchmarking sessions.
Then we replayed back that traffic and hit the machines in our lab with thousands of concurrent users generated by Tsung.
The cool thing is that we could produce test scenarios that look closer to what's happening in the real production environment. I'd like to thanks Alvaro Videla for this excellent write up.
If you would like to share the architecture for your fablous system, please contact me and we'll get started. Let's do the math. They have 28 PHP boxes with processes each.
You need as many PHP processes as you need to be able to handle concurrent requests not per second. That means either their scripts take 1 second to execute each or they have way to many processes.
Either way something is broken. Quote: This system lets us improve the resource management. No that does not mean you have concurrent updates.
Most of the time a lot less. Also note they have 50 memcached nodes. How many servers do they have to handle this moderate amount of load?
It's insane. Conclusion: not impressive and I have not seen any new insights. I question the efficience of their code a lot.
Hi Alvaro, thanks for that interesting insight in your architecture. Can you provide a link to Graphite? It sounds interesting, and we're beginning to look at those systems, but its such a common word that simple Googles aren't coming up with anything that I think is correct.
Not How many partials components do they show? Is the site information completely dynamic? And the list of questions can go on.
