last week, i had the good fortune to attend the san francisco nosql meetup organized by johan oskarsson.

the meetup discussed the limitations of traditional relational database technology at scale and the open-source alternatives currently available with similar functionality to amazon's dynamo google's bigtable.

the presentations were all outstanding. todd lipcon from cloudera also gave a great overview of the space, basic principles and what to look out for when evaluating these technologies. this was followed by a series of detailed talks on individual technologies: jay kreps on voldemort, avinash lakshman on cassandra, cliff moon on dynomite, ryan rawson on hbase, doug judd on hypertable and chris anderson on couchdb.

i tried to record them all but had some camera issues. i've included what i managed to get below for your viewing pleasure. todd's talk is a great place to start.

check out johan's blog for slides and more videos.
