"GemStone Systems » We Solve the Hardest Problems - java caching,
distributed caching and event processing"
"In addition to these prior art approaches by Web 2.0 vendors,
GemStone’s perspective on distributed system design is further
illuminated by 25 years of experience with customers in the world of
high finance. Here, in stark contrast to Web user-oriented applications,
financial applications are highly transactional, automated, and
consistency of data is paramount. Eventually consistent solutions are
frequently not an option. Business rules do not permit relaxed
consistency, so invariants like account trading balances must be
enforced by strong transactional consistency semantics. In application
terms, the cost of an apology makes rollback too expensive, so many
high-speed financial applications must limit workflow exposure
traditionally by relying on OLTP systems with ACID guarantees."
This desire for all of Consistency, Availability, and Partionability
(CAP) mentioned in the link (saying all real systems are tradeoffs
between those), especially to manage financial data, perhaps flows out
of a scarcity paradigm for our society? You can't just accept having a
peer-to-peer gift economy in our dominant culture right now -- you need
accurate accounting that relates to "ownership" of resources perceived
Ironically, fiat dollars that are just blips in computer memory and
could be arbitrary amounts -- fiat dollars are artificially scarce by
design, and these systems built on abundant computing are being designed
to enforce that artificial scarcity.
So, here we see a technical need for database architecture driven by a
social paradigm of scarcity and "ownership" and a desire for a high
degree of globe spanning control. So, here is a crossover between my
thinking about the Pointrel system and notions of abundance.
"The Mythology of Wealth"
The biggest challenge of the 21st century is the irony of technologies
of abundance in the hands of those thinking in terms of scarcity.
