Eclipse DataGrid

The Eclipse DataGrid project delivers a high-performance, distributed, in-memory data processing layer for Java applications. Built upon the robust foundation of EclipseStore, Eclipse DataGrid extends its capabilities to enable seamless replication and distribution of native Java object graphs across multiple JVMs in a cluster. This innovative approach empowers developers to leverage the full potential of the Java language and JVM, eliminating the impedance mismatch and performance bottlenecks associated with traditional data solutions.

Eclipse DataGrid can also be seamlessly integrated into existing database application infrastructures, acting as an in-memory caching, searching and data processing layer to significantly improve performance, reduce the load on primary databases, and lower overall database infrastructure costs, including potential savings on database license fees. Target group are both, Java enterprise and cloud-native application builders.

1. Project Goals

• Provide Java-Native In-Memory Data Processing: To offer a distributed Java in-memory data processing layer, that is deeply integrated with the Java language, utilizing core Java features and the native Java object model.
• Eliminate Impedance Mismatch: To remove the need for complex and inefficient mappings between Java objects and external data formats or structures.
• Use JVM Performance for In-Memory Data Processing: To enable applications to achieve microsecond-level look-up, response, and query times by leveraging the performance of the JVM’s runtime, memory management, and JIT compiler.
• Simplify Distributed Java Development: To provide a straightforward way for Java developers to work with distributed Java object graphs, data and clusters, using familiar Java concepts and tools.
• Offer ACID Compliance in a Distributed Environment: To ensure data consistency and reliability in clustered deployments by using EclipseStore's ACID properties.
• Optimize Database Performance and Costs: To enable the use of Eclipse DataGrid as a caching, searching, and processing layer, reducing the load on underlying databases and lowering infrastructure expenses.
• Support of any Programming Language: A REST interface enables access Eclipse DataGrid with any program language.

2. How the Project Works

Eclipse DataGrid comprises several key components that work together to provide a distributed Java in-memory data processing solution:

• Java Object Graph Model: Unlike traditional key-value-based data grids, Eclipse DataGrid preserves Java’s object-oriented paradigm, enabling developers to work with complex object graphs without sacrificing performance or simplicity. Eclipse DataGrid replicates this graph across the cluster, allowing distributed access to the data. The Java object graph is used as an in-memory data storage system at runtime that enables execution of CRUD operations and a rollback mechanism.
• Java Streams API and Lucene: Eclipse DataGrid leverages Java's Streams API for efficient data searching, filtering, and manipulation. It will also integrate Lucene for advanced full-text search capabilities.
• Indexing: A special HashMap enables indexing and fully-automated lazy-loading to minimize I/O traffic.
• EclipseStore Integration: The integration of EclipseStore provides ACID-compliant persistence to all Eclipse DataGrid nodes.
• Replicate Java Object Graphs: Eclipse DataGrid extends EclipseStore by providing a specific storage function that can distribute the storage process of an object graph across multiple JVMs within a cluster via event streaming. The standard consistency model is eventual consistency. In a later version, a configurable strong consistency model is provided.
• Kubernetes Integration: A dedicated Helm chart will be provided to facilitate the creation, setup, and provisioning of a cluster environment on Kubernetes. This streamlines the deployment and management of Eclipse DataGrid in modern, cloud-native environments.
• Management GUI: A Java application with a graphical user interface will be developed to simplify cluster operations. This GUI will enable users to:
  
  • Provision and set up Eclipse DataGrid clusters.
  • Perform ongoing maintenance of the cluster.
  • Monitor cluster health and performance using observability tools (e.g. Grafana, Prometheus)
  • Troubleshoot issues that may arise.
