一个 Geode 分布式系统由跨网络的成员节点组成, 提供内存速度, 带有高可靠, 高扩展性, 和容错. 每个成员基于JVM, 管理数据和计算逻辑, 连接到其他 Geode 成员. Members hosting data maintain a cache consisting of one or more Regions that can be replicated or partitioned across the distributed system. Compute logic is deployed to members as needed by adding the appropriate Java JAR files to the member’s class path管理数据的成员维护一个缓存, 缓存中的Region 可以跨分布式系统进行复制或分区. 计算逻辑被部署到添加合适 Java JAR 文件的成员上.

使用 Geode 的公司:

• 减少风险分析从6 小时到 20 分钟, 在闪电崩盘的过程中能够记录下交易资料, 而其他机构都不能够做到这一点.
• 增强的最终用户响应时间, 从3秒到 50 毫秒, 一年能够增加 8 位数的收益, 而项目交付小于6个月.
• 实时追踪资产, 协调对的人和机器在对的时间到达对的地点, 发挥高价值的机会.
• 创建用户预留系统, 每天可以处理10亿的请求
• Reduced risk analysis time from 6 hours to 20 minutes, allowing for record profits in the flash crash of 2008 that other firms were not able to monetize.
• Improved end-user response time from 3 seconds to 50 ms, worth 8 figures a year in new revenue from a project delivered in fewer than 6 months.
• Tracked assets in real time to coordinate all the right persons and machinery into the right place at the right time to take advantage of immediate high-value opportunities.
• Created end-user reservation systems that handle over a billion requests daily with no downtime.

Geode 通信

Geode 成员使用 TCP, UDP 单播和 UDP 多播相结合的方式进行成员之间的通信. Geode 成员与其他成员之间维护着经常性通信 , 为了分发数据和管理整个分布式系统.
