Questions tagged [geode]

Apache Geode is an open source, distributed in-memory database for scale-out applications that is a top level project at The Apache Software Foundation. Apache Geode started with a 1 million code line grant by Pivotal Software of much of the Pivotal GemFire commercial code base.

Geode is a data management platform that provides real-time, consistent access to data-intensive applications throughout widely distributed cloud architectures.

Geode pools memory (along with CPU, network and optionally local disk) across multiple processes to manage application objects and behavior. It uses dynamic replication and data partitioning techniques for high availability, improved performance, scalability, and fault tolerance. Geode is both a distributed data container and an in-memory data management system providing reliable asynchronous event notifications and guaranteed message delivery.
