db4o

Improvements were made to the db4o Replication System (dRS) to also allow replication between db4o and Versant Object Database (VOD) in addition to db4o to db4o replication and to relational databases.

This development release features lightning fast operation with a new B-Tree Id system, a pluggable Id system, transparent activation for .NET collections, and more.

This release comes with new monitoring support to collect runtime statistics about performance relevant behavior and state. Statistics are published through the Performance Counters API. You can now use the PerfMon monitoring tool to view graphed information about queries, the free space manager, the object reference system, IO, and networking. Since this is still a work in progress, you may expect to see changes in the API and the list of actual statistics supported.

This release comes with new monitoring support to collect runtime statistics about performance relevant behavior and state. Statistics are published through Java Management Extensions (JMX). You can now use jconsole or a similar JMX monitoring tool to view graphed information about queries, the free space manager, the object reference system, IO, and networking. Since this is still a work in progress, you may expect to see changes in the API and the list of actual statistics supported.

This release comes with an optimized
implementation of LINQ (Language INtegrated
Queries). Solution files for Visual Studio 2008
are provided along with the sources. The latest
work on Transparent Activation (TA) and
Transparent Persistence (TP) is included. Db4oTool
was improved to make optimization for Native
Queries and for TA/TP easier. Optimizations can
also be called with msbuild.
