Introduction: If you look at the early days of this blog, when web scalability was still in its heady bloom of youth, many of the articles had to do with leveraging MySQL and memcached . Exciting times. Shard MySQL to handle high write loads, cache objects in memcached to handle high read loads, and then write a lot of glue code to make it all work together. That was state of the art, that was how it was done. The architecture of many major sites still follow this pattern today, largely because with enough elbow grease, it works. This was a pre-cloud, relational database dominated world, built from parts scrounged from the remnants of enterprises and datacenters past. Twitter and Digg started in this era, but are evolving into something different, as scaling pressures increase and new purpose built technologies pop into being. With a little perspective, it's clear the MySQL+memcached era is passing. It will stick around for a while. Old technologies seldom fade away completely. Some still

2 0.19583477 927 high scalability-2010-10-26-Marrying memcached and NoSQL

Introduction: Memcached  is one of the most common In-Memory cache implementation.  It was originally developed by  Danga Interactive  for  LiveJournal , but is now used by many other sites as a  side cache  to speed up read mostly operations. It gained popularity in the non-Java world, too, especially since it’s a language-neutral side cache for which few alternatives existed.   As a side-cache, Memcache clients relies on the database as the system of record, The database is still used for write,update and complex query operations.  Since the  memcached specification includes no query operations, memcached is not a database alternative, unlike most of the NoSQL offerings. It also exclude memcache from being a real solution for write scalability. As a result of that many of the heavy sites started to move away from Memcache and replace it with other NoSQL alternatives as noted in a recent highscalability post  MySQL And Memcached: End Of An Era? The transition away from memcached to NoSQL

3 0.17787756 360 high scalability-2008-08-04-A Bunch of Great Strategies for Using Memcached and MySQL Better Together

Introduction: The primero recommendation for speeding up a website is almost always to add cache and more cache. And after that add a little more cache just in case. Memcached is almost always given as the recommended cache to use. What we don't often hear is how to effectively use a cache in our own products. MySQL hosted two excellent webinars (referenced below) on the subject of how to deploy and use memcached. The star of the show, other than MySQL of course, is Farhan Mashraqi of Fotolog. You may recall we did an earlier article on Fotolog in Secrets to Fotolog's Scaling Success , which was one of my personal favorites. Fotolog, as they themselves point out, is probably the largest site nobody has ever heard of, pulling in more page views than even Flickr. Fotolog has 51 instances of memcached on 21 servers with 175G in use and 254G available. As a large successful photo-blogging site they have very demanding performance and scaling requirements. To meet those requirements they've developed a

4 0.1656552 729 high scalability-2009-10-28-And the winner is: MySQL or Memcached or Tokyo Tyrant?

Introduction: Matt, from the ever excellent MySQL Performance Blog , decided to run a test using a simple scenario drawn from his client experience in the gaming space. The scenario: read a row based on a primary key, update the row, write it to disk, and use the row to lookup another row. Matt ran three different tests explained in a series of three different articles: MySQL and MySQL + Memcached,   Memcached Only , and Tokyo Tyrant . The lovingly compiled details along with many cool graphs are in the articles, but in general the lessons learned are: When memcached has enough memory (so records being accessed are in RAM), memcached + MySQL can provide a 10x performance boost over MySQL alone. When the RAM is too small and hot records, those being accessed a lot, aren't in RAM, or perhaps applications are doing a sequential scan of a table and the entire table isn't cached, then memcached won't be the big bang improvement you may be hoping for. When the database is removed and memcac

5 0.16404191 954 high scalability-2010-12-06-What the heck are you actually using NoSQL for?

Introduction: It's a truism that we should choose the right tool for the job . Everyone says that. And who can disagree? The problem is this is not helpful advice without being able to answer more specific questions like: What jobs are the tools good at? Will they work on jobs like mine? Is it worth the risk to try something new when all my people know something else and we have a deadline to meet? How can I make all the tools work together? In the NoSQL space this kind of real-world data is still a bit vague. When asked, vendors tend to give very general answers like NoSQL is good for BigData or key-value access. What does that mean for for the developer in the trenches faced with the task of solving a specific problem and there are a dozen confusing choices and no obvious winner? Not a lot. It's often hard to take that next step and imagine how their specific problems could be solved in a way that's worth taking the trouble and risk. Let's change that. What problems are you using NoSQL to sol

2 0.8284651 770 high scalability-2010-02-03-NoSQL Means Never Having to Store Blobs Again

Introduction: Morgan Tocker has an awesome article and comment thread in the MySQL Performance Blog about When should you store serialized objects in the database? Before the NoSQL age is was very common to simulate schemalessness by storing blobs in MySQL. Sharding was implemented by running multiple MySQL instances and spreading writes across them. While not ideal for the purpose, developers felt comfortable with MySQL. They knew how to install it, back it up, replicate it, in short:  they knew how to make it work. Yet they also needed to store objects without the penalty of joins. Searches and aggregate queries were handled by indexes kept in separate tables, this offloaded the fast path to objects. This all made perfect sense. Usually we just want stuff to work and going with what you know is often the best path to that goal. And what we have known is MySQL. All the different pros and cons of this approach are covered wonderfully in the post. But the world has changed. With the same goal

3 0.80651802 1025 high scalability-2011-04-16-The NewSQL Market Breakdown

Introduction: Matt Aslett from the 451 group created a term called “NewSQL ”. On the definition of NewSQL, Aslett writes: “NewSQL” is our shorthand for the various new scalable/high performance SQL database vendors. We have previously referred to these products as ‘ScalableSQL’ to differentiate them from the incumbent relational database products. Since this implies horizontal scalability, which is not necessarily a feature of all the products, we adopted the term ‘NewSQL’ in the new report. And to clarify, like NoSQL, NewSQL is not to be taken too literally: the new thing about the NewSQL vendors is the vendor, not the SQL. As with NoSQL, under the NewSQL umbrella you can see various providers, with various solutions. I think these can be divided into several sub-types: New MySQL storage engines . These give MySQL users the same programming interface, but scale very well. You can Xeround or Akiban in this field. The good part is that you still use MySQL, but on the downside it’s n

Introduction: Michael Stonebraker sure knows how to stir up a storm. Unlike for others, that doesn't make him a troll in my mind, he's way too accomplished in the field to be that, but he does have a bit of Barnum & Bailey in him, which serves to get the discussion flowing, and that's a good thing. A lot of previously hidden wisdom and passion unlocks, which we'll try to capture here. This disturbance in the force is over OldSQL vs NoSQL vs NewSQL . Warning, these are not crisp categories, there's leakage all over the place, watch your step: OldSQL  (Oracle, MySQL, etc) refers to what some want to term as legacy relational database like MySQL, that don't scale out horizontally with aplomb. NoSQL  (CouchDB, Redis, Cassandra, HBase, MongoDB, Riak, Neo4j, etc) refers to, well, a collection of technologies that aren't OldSQL, these often are designed to scale out horizontally, aren't on ACID, and use schemaless non-relational datamodels.

Introduction: What will the version of the Internet that follows us to the stars look like? Yes, people are really thinking seriously about this sort of thing. Specifically the  InterPlanetary Networking Special Interest Group (IPNSIG). Ansible-like faster-than-light communication it isn't. There's no magical warp drive. Nor is a network of telepaths acting as a 'verse spanning telegraph system. It's more mundane than that. And in many ways more interesting as it's sort of like the old Internet on steroids, the one that was based on on UUCP and dial-up connections, but over vastly longer distances and with much longer delays : The Interplanetary Internet (based on IPN, also called InterPlaNet) is a conceived computer network in space, consisting of a set of network nodes which can communicate with each other.[1][2] Communication would be greatly delayed by the great interplanetary distances, so the IPN needs a new set of protocols and technology that are tolerant to large delays and

Introduction: How do you design a reliable distributed file system when the expected availability of the individual nodes are only ~1/5? That is the case for P2P systems. Dominik Grolimund, the founder of a Swiss startup Caleido will show you how! They have launched Wuala , the social online storage service which scales as new nodes join the P2P network. The goal of Wua.la is to provide distributed online storage that is: large scalable reliable secure by harnessing the idle resources of participating computers. This challenge is an old dream of computer science. In fact as Andrew Tanenbaum wrote in 1995: "The design of a world-wide, fully transparent distributed filesystem fot simultaneous use by millions of mobile and frequently disconnected users is left as an exercise for the reader" After three years of research and development at at ETH Zurich, the Swiss Federal Institute of Technology on a distributed storage system, Caleido is ready to unveil the resu
