Sleepycat Announces the Release of Berkeley DB 4.0

From the press release: “Sleepycat Software, Inc. today announced the release of version 4.0 of the award-winning data management system, Berkeley DB. Version 4.0 delivers new services and significant performance enhancements for high-end mission critical applications. Berkeley DB 4.0 provides a new feature required by developers building mission-critical applications: High Availability. Designed for applications that must run around the clock, High Availability uses a technique called “replication” to keep multiple copies of a database, stored in different places, up to date. In the event of a hardware or application crash that causes one of the copies to fail, applications can use the remaining copies to continue operating without interruption. Application developers can also use the copies to answer queries during normal operation. As a result, applications can support more users more reliably than ever before.”
