------------------------------------
Summary: Investigate concurrency improvements to DerbyObservable
and DerbyObserver
Key: DERBY-6891
URL: https://issues.apache.org/jira/browse/DERBY-6891
Project: Derby
Issue Type: Improvement
Components: Store
Reporter: Rick Hillegas
As part of derby-6856, we introduced a pair of classes which manage callbacks
between classes in the Store layer. The classes are DerbyObservable and
DerbyObserver. They replace the deprecated Observer and Observable classes in
the JVM and allow Derby to build without deprecation warnings. Right now,
callbacks are managed by a Vector. It is quite likely that the concurrency of
these classes (and therefore of the Store layer) could be boosted by using some
mechanism from java.util.concurrent.
