How Twitter Is Moving To the Cassandra Database
MyNoSQL has up an interview with Ryan King on how Twitter is transitioning to the Cassandra database. Here's some detailed background on Cassandra, which aims to "bring together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model." Before settling on Cassandra, the Twitter team looked into: "...HBase, Voldemort, MongoDB, MemcacheDB, Redis, Cassandra, HyperTable, and probably some others I'm forgetting. ... We're currently moving our largest (and most painful to maintain) table — the statuses table, which contains all tweets and retweets. ... Some side notes here about importing. We were originally trying to use the BinaryMemtable interface, but we actually found it to be too fast — it would saturate the backplane of our network. We've switched back to using the Thrift interface for bulk loading (and we still have to throttle it). The whole process takes about a week now. With infinite network bandwidth we could do it in about 7 hours on our current cluster." Relatedly, an anonymous reader notes that the upcoming NoSQL Live conference, which will take place in Boston March 11th, has announced their lineup of speakers and panelists including Ryan King and folks from LinkedIn, StumbleUpon, and Rackspace.
I know you're being sarcastic, but I think some of us around here really do look forward to a non-functioning twitter. Maybe, if it's down long enough, everyone will take a step back and realize what a complete tool they've been, telling the world how their last coffee was, where the Best Place to Buy Things is, or some other third thing equally mundane and self serving.
Here's to them royally screwing up!
There's a 68.71% chance you're right.
In general your attitude reminds me of the people who thought personal computers would always be toys. "Proper work" would be done on mainframes/supercomputers and trivial office tasks may as well be done on paper. Well, mainframes / supercomputers are still faster than personal computers, but few people would claim the PC had no impact on the office.
- in general your attitude reminds me of everyone who ever thought that the latest fad is the silver bullet that will devoid them of any responsibility for a hacky design and kludgy implementation, all sprinkled with hair bossy management attitude. Good luck with your new silver bullet, hope you kill the vampire of incompetence.
You can't handle the truth.
