- Where do you keep your persistent data? We've had two main options so
- far: file systems (FSs) and database management systems (DBMSs). For many of
- us, neither choice is good enough.
-
- On one hand, FSs are often unreliable, provide no data consistency, few
- offer versioning, sharing is primitive at best, and you have to keep
- transforming data between "internal" and "external" forms all the time. But
- they are fast, they can hold any data, they are easy to use, and -- the price
- is right!
-
- On the other hand, true DBMSs support sharing and data integrity,
- transactions and versioning (although the specifics may not be exactly what
- your application needs), are scalable, and tend to be more robust. But they
- are slower by an order of magnitude or more, they confine you to the kind of
- data they happen to know about (or you may impose any structure on a BLOB --
- back to where you were with files, only much slower), they are hard to use,
- quite complicated, and -- expensive in money, system resources, and operational
- costs!
-
- Not a bright picture in the economics of quality! Is there a happy medium?
- Something with the speed and flexibility of files, the reliability,
- shareability and robustness of databases, and a cost that won't break your
- wallet or the available hardware? Sure there is! A new class of products, the
- Persistent Data Servers, point to that direction.
-
- We will introduce Kala, the first commercial persistent data server. This
- brief presentation will cover the basics of the Kala model, as well as an
- application example.
