[jira] Created: (DERBY-698) Use Java 5 concurrent collections for better concurrency (rather than synchronized collections)
Use Java 5 concurrent collections for better concurrency (rather than synchronized collections)
-------------------------------------------------------------------------------------------------
Key: DERBY-698
URL: http://issues.apache.org/jira/browse/DERBY-698
Project: Derby
Type: Improvement
Reporter: David Van Couvering
The new Java 5 concurrency utilities includes a set of concurrent collections that allow for greater concurrency than the current synchronized collections we are using. This could provide performance improvements for Derby, particularly in CMT (chip multi-threading) architectures.
