LinkedIn: Creating A Low Latency Change Data Capture System With Databus
This is a guest post by Siddharth Anand, a senior member of LinkedIn's Distributed Data Systems team. Over the past 3 years, I've had the good fortune to work with many emerging NoSQL products in the context of supporting the needs of a high-traffic, customer facing web site. In 2010, I helped Netflix to successfully transition its web scale use-cases from Oracle to SimpleDB, AWS' hosted database
NoSQL Data Modeling Techniques
NoSQL databases are often compared by various non-functional criteria, such as scalability, performance, and consistency. This aspect of NoSQL is well-studied both in practice and theory because specific non-functional properties are often the main justification for NoSQL usage and fundamental results on distributed systems like the CAP theorem apply well to NoSQL systems. At the same time, NoSQL
Why does Quora use MySQL as the data store instead of NoSQLs such as Cassandra, MongoDB, or CouchDB? Are they doing any JOINs over MySQL?...
Answer (1 of 36): 1. If you partition your data at the application level, MySQL scalability isn't an issue. Facebook reported [1] running 1800 MySQL servers with just two DBAs in 2008. You can't do joins across partitions, but the NoSQL databases don't allow this anyway. Facebook hasn't confirmed...

Using MySQL as a NoSQL - A story for exceeding 750,000 qps on a commodity server
UPDATE: Oracle officially released memcached daemon plugin that talks with InnoDB. I'm glad to see that NoSQL+MySQL has become an official solution. It's still preview release but will be very promising. Let's try it to make it better! Most of high scale web applications use MySQL + memcached. Many of them use also NoSQL like TokyoCabinet/Tyrant. In some cases people have dropped MySQL and have sh
