Soundbites: the Facebook/MySQL/NoSQL/VoltDB/Stonebraker flap, continued

As a follow-up to the latest Stonebraker kerfuffle, Derrick Harris asked me a bunch of smart followup questions. My responses and afterthoughts include:

Continuing with that discussion of DBMS alternatives:

And while we’re at it — going schema-free often makes a whole lot of sense. I need to write much more about the point, but for now let’s just say that I look favorably on the Big Four schema-free/NoSQL options of MongoDB, Couchbase, HBase, and Cassandra.

Notes on short-request scale-out MySQL

A press person recently asked about:

… start-ups that are building technologies to enable MySQL and other SQL databases to get over some of the problems they have in scaling past a certain size. … I’d like to get a sense as to whether or not the problems are as severe and wide spread as these companies are telling me?

Introduction to Tokutek

Tokutek has a paradoxical pitch: Tokutek writes data particularly quickly, and therefore you’re supposed to buy Tokutek for query-oriented uses. Highlights of the Tokutek story include:

Tokutek’s initial target market is the usual combination of clickstream/personalization/other network management. The idea is that many data warehouse technologies have trouble getting latency below, say, 15 seconds to 5 minutes, at least at very high update volumes. So if immediacy is more important than raw complex query performance, Tokutek’s performance profile could be attractive. Read more
