eXtremeDB 5.0 Embedded DBMS, with Improvements in Clustering, Speed and Developer Efficiency, Available Now
May 1st 2013. The latest version of the McObject’s eXtremeDB embedded database system is now available from Phaedrus Systems. eXtremeDB 5.0 has new features that make eXtremeDB’s clustering faster and more flexible, and further simplify its administration.
“eXtremeDB Cluster is already deployed in fields ranging from aerospace/defence to smart grid management and financial systems,” commented Phaedrus CTO, Chris Hills. “The improvements in eXtremeDB 5.0 mean it can address an even wider range of real-time computing challenges.”
New features in eXtremeDB Cluster 5.0 include:
A local tables option that exempts specified eXtremeDB tables from cluster-wide replication, to accelerate processing at the local node. Local tables are shareable, when desired, through a scatter/gather mechanism
Dynamic clustering, which enables nodes to join and leave clusters without interrupting processing. This further simplifies administration for a clustering database technology that counts minimal run-time maintenance as a defining characteristic
Support for Infiniband switched fabric interconnect. Infiniband reduces communication latency between eXtremeDB Cluster nodes and improve throughput and scalability
Support for the Message Passing Interface (MPI) standard, which increases messaging efficiency for parallel processing on distributed-memory systems (i.e. clusters) to deliver higher speed and scalability. Open and widely-used, MPI provides the additional benefits of developer familiarity and more portable code
In McObject’s tests, eXtremeDB Cluster using Infiniband and MPI performed more than 7.5x faster than the same system implemented with “plain vanilla” gigabit networking (TCP/IP and Ethernet). MPI can also be used over Ethernet-TCP, and in McObject’s tests this combination performed almost 1.5x faster than using TCP/IP over Ethernet. eXtremeDB Cluster’s Infiniband and MPI support is provided on Linux in the current release.
Other new features in version 5.0 reduce DBMS latency, and improve developer efficiency, in all eXtremeDB editions. Newly supported NUMERIC and DECIMAL data types provide more precise calculations than alternative FLOAT and DOUBLE types. By permitting integer operations, NUMERIC and DECIMAL data types enable faster performance while also allowing the database designer to specify the exact scale and precision required.
eXtremeDB 5.0 also adds support for nullable data types, or the ability to set data types to the special value NULL. This provides greater flexibility in representing missing or inapplicable information in query results. eXtremeDB’s NULL value support extends to both its SQL and native C/C++, Java and .NET application programming interfaces (APIs).
For the growing community of developers using eXtremeDB with the Java and .NET languages, version 5.0 adds features that increase flexibility, programming efficiency and performance. These include:
.NET and Java class generators. eXtremeDB’s database schema compiler, inistic garbage collection and is optimized for critical systems such as controls and visualization
Compatibility of eXtremeDB’s Java Database Connectivity (JDBC) API with JDK 7
Version 5.0 also improves eXtremeDB High Availability, McObject’s DBMS edition that implements master-replica database replication and serves as the basis of many fault-tolerant systems. eXtremeDB 5.0 adds High Availability functions that improve an application’s ability to control failover to a replica, by providing greater control to the replica over closing the communication channel to the master.
