Will the data center of the future have no central UPS units, and be filled with servers with on-board batteries? The data center team at Facebook believes it should.
Facebook Engineering Amir Michael, a server and datacenter engineer at Facebook, explains how thinking differently can lead to significant gains in cost and energy efficiency.
With Facebook users spending a collective 8 billion minutes on the site each day, serving 1.2 million photos each second, and managing more than 25 terabytes of data per day in logging data, we're forced to think about servers and datacenters differently.

At the end of this note I describe how InnoDB can be much faster (2.5X) for high-concurrency workloads. However, what we really did is improve the code to not get 2.5X slower. InnoDB uses innodb_thread_concurrency to limit the number of threads that run concurrently...

Apache Hive is a data warehouse built on top of Apache Hadoop, that provides tools to enable easy data summarization, adhoc querying and analysis of large datasets data stored in Hadoop files. It provides ...
I was debugging a server that had too many concurrent queries. From SHOW INNODB STATUS output, there were many long running transactions with uncommitted work and there were many more transactions blocked on InnoDB locks...
