Oct. 26, 2010 SDF Membase NoSQL Cloud Solution

On October 26, 2010 in Menlo Park at Orrick, the SDForum Cloud Services SIG hosted Matt Ingenthron of Membase’s presentation “Scale out NoSQL Solution for the Cloud.”

Apps are moving from the desktop to the cloud, with millions of users expecting instantaneous response. Membase offers new techniques to store and retrieve data in the NoSQL space. They offer a simple, fast, elastic key-value database based on the memcached engine interface and compatible with existing memcached clients and applications. This is Open Source under an Apache 2.0 license and can scale in public or private clouds.

It was originally used to speed up access to authoritative data as a distributed hashtable. It can scale linearly by adding nodes without losing access to data and still maintain consistency when accessing. The scaling flattens out the cost and performance curves that would make traditional DBMS grind to a halt. This proved crucial when supporting such social games a Farmville and Mafia Wars. The Membase server database can handle 500,000 ops per second.

Ingenthron wrapped up by discussing Project Arcus, Moxi (memcached proxy), vBucket mapping, and clustering. He mentioned their partnership with Cloudera using Sqoop and Flume with Hadoop. Membase offers the distributed OLTP solution and Cloudera offers the distributed OLAP solution. As an example, an ad targeting to a particular user that might normally take 40 milliseconds could take only one millisecond. This could make a big difference when traveling across a crowded mobile network.
