This document discusses different categories of NoSQL databases and provides examples. It also introduces the Membase distributed key-value store and describes how it is simple, fast, and elastic. Details are given on getting involved with the open source project, including using pre-built packages, platform porting opportunities, and contact information.

8. NoSQL stores
•MapReduce batch oriented: Google
MapReduce; Cloudera/Hadoop MapReduce
•multi-dimensional sorted map: Google BigTable,
Hadoop HBase
•eventually consistent key-value: Amazon
Dynamo, Voldemort, Basho Riak
•column oriented, eventually consistent: Apache
Cassandra
•distributed, consistent key-value: membase

Simple
Fast
Elastic

10. Simple: key-value

11. Fast: memcached like speed

12. elastic: just throw
another puppy at it

13. The project/getting involved
• Open Source
• Nearly all Apache 2.0 licensed
• Some components BSD based, owing to history
• Try using it!
• RPM for RHEL/CentOS 5.2 and later
• .deb for Ubuntu 9.04
• Looking for platform porting
• Have some RedHat/CentOS, Ubuntu covered
• Could certainly integrate a bit better
• Especially needed with moxi
