  • In the old days all your structured data storage requirements went into the classic RDBMS like DB2, Oracle, Sybase, InformixRelational databases were great! You could define data structures and insert, join them to your hearts content and query them to give you the bits of data you want. After a while you joins become a massive chain and your systems start slowing down! Change the data structure to perform better? Too risky!Noooo, just buy more kit to make it perform!Then there is the multi data centre configuration. What did we used to do in the past? SAN replication? Oracle replication? There was a lot of operational headaches there.Anyway, while Larry was busy eating his hot dog, TCP/IP became more popular, ISP’s started appearing, Mosaic Browsers started appearing on people’s home PC’s, the whole internet revolution happened! So clever guys such as Larry and Sergei, and brave guys like Jeff Bezos were busy building global scale services. They hired a whole bunch of really clever engineers and gave them the global scale problems to solve. How many of you guys here who had a boss saying, I’ve got an e-commerce website, write a database engine that scales globally? That was the sort of bold move these have made back then. And what’s good about them is that rather than keeping all of this their trade secret, they started publishing papers on their implementations.Then this guy came along, stole Amazon Dynamo DB engineer AvinashLakshman, and built Cassandra, and eventually had it open sourced.Next slide
