Database Reference
In-Depth Information
We covered distributed transactions and how they differ from single database transactions. We explored the
limitations imposed upon us in a distributed transaction and discussed why they exist. Before you build a distributed
system, you need to understand these limitations. What works in a single instance might not work in a distributed
database.
The chapter closed with a look at autonomous transactions and covered what they are and, more important,
when they should and should not be used. I would like to emphasize once again that the legitimate real-world use of
autonomous transactions is exceedingly rare. If you find them to be a feature you are using constantly, you'll want to
take a long, hard look at why.
