MegaData
Joe Gregorio - ETech '07 Summary - Part 2 - MegaData:
"If you want to scale to the petabyte level, or the billion requests a day, you need to be:
- Distributed
- The data has to be distributed across multiple machines.
- Joinless
- No joins, and no referential integrity, at least at the data store level.
- De-Normalized
- No one said this explicily, but I presume there is a lot of de-normalization going on if you are avoiding joins.
- Transcationless
- No transactions
Those constraints represent something fundamentally different from a relational database."
