Next Generation Data Fabric Delivers Massive Scalability and Improved Performance for Distributed Systems

GemStone Systems, the leading provider of the Enterprise Data Fabric (EDF), today introduced GemFire 5.0. Designed specifically to meet the demanding performance and scalability requirements of advanced J2EE, grid, SOA and OLTP applications, GemFire Enterprise 5.0 provides a high-performance, distributed operational data store that enables real-time operations across distributed locations. The unprecedented scalability features of GemFire Enterprise 5.0 enable organizations to manage massive data loads while guaranteeing data integrity and availability to power mission-critical applications. By enabling applications to scale transparently, GemFire Enterprise 5.0 guarantees operational reliability while preventing single points of failure and managing exceptions without widespread impact.

“Enterprises are facing the growing challenges of using disparate sources of data managed by different applications,” noted Noel Yuhanna, Forrester Research. “New technology is emerging that Forrester has coined "information fabric," a term defined as a virtualized data layer that integrates heterogeneous data and content repositories in real time. The potential benefits of this technology are so great that enterprises should develop a strategy to leverage information fabric technology as it becomes more widely available.”

As the core component of the GemFire Enterprise Data Fabric, this release combines essential components of databases, messaging and caching, providing distributed data virtualization and sharing to counter the real-world deployment challenges of complex application systems, wherein a single offending member can bring the entire system to a grinding halt. GemFire Enterprise 5.0 provides scalability along three distinct elements - data scalability, distribution scalability, and cluster/membership scalability – without compromising performance.

“SOA and grid computing projects frequently present dramatic data management challenges, requiring reliable access and delivery of data among disparate applications with minimum latency,” said Shankar Iyer, executive vice president, marketing and strategy, GemStone Systems. “The new features and improved functionality of GemFire 5.0 reliably and consistently manage data persistence and distribution across several hundreds or thousands of nodes, providing a distributed data layer to maximize deployments.”

Leveraging standards based querying and optimized, native data management, GemFire Enterprise is built on one of the industry’s fastest and most reliable data distribution and caching systems. New features of 5.0 include:

Role-based reliable data distribution

GemFire Enterprise 5.0 boasts innovative role-based reliable data distribution, providing a user-defined method for managing data routing while offering advanced levels of reliability and consistency across large scale, dispersed deployments. This feature enables application architects to define “roles” related to specific cache members and further identify certain roles as “required roles” for a particular cache node. In this manner application dependencies can be modeled at the infrastructure level to guarantee reliability and data consistency in a configurable manner.

Enhanced data portioning model

By combining previously available data portioning schemes with data region semantics used to define and describe logical data namespaces, 5.0 enables interoperability between partitioned and non-partitioned regions within a distributed system. User-defined policies/configurations control the memory management and redundancy performance of the partitioned regions to handle node failures, redirecting the affected client requests automatically to a back-up node, allowing architects to dynamically scale their applications to increasing data loads.

Loosely coupled distributed systems

5.0 offers an innovative gateway hub/gateway model to connect and configure distributed systems and/or sites across Wide Area Network (WAN) in a loosely coupled fashion, delivering unlimited scalability. This model enables each GemFire distributed system to assign a process as its gateway hub, which includes multiple gateways that connect to other distributed systems. Back-up gateways and gateway hubs can be created and configured to manage automatic fail-over, ensuring data consistency with no performance degradation.

Advanced management for slow and unresponsive applications

GemFire Enterprise 5.0 provides advanced management for slow and unresponsive applications to maintain a superior quality of service across distributed systems. There are no adverse effects to overall system performance and throughput if any one application/server consumes messages at a slower rate than other receivers. 5.0 allows a distribution timeout to be associated with each consumer, automatically switching from the default synchronous communication mode to an asynchronous mode if message acknowledgements are not received within the timeout period.
