为什么选择云数据库 GeminiDB

高弹性，实现计算分钟级扩容，存储秒级扩容

Shared Nothing + Shared Storage 架构：多个无状态的计算节点共享一个有状态的分布式存储引擎
高资源利用率：集群动态负载均衡，由内部proxy集群提供数据的动态负载均衡
弹性极致扩容：一键下发任务，计算资源分钟级扩容，存储空间秒级扩容

高可靠，保障企业级数据0丢失，性能稳定

数据 0 丢失 & 强一致：GeminiDB基础组件服务实现数据三副本冗余，确保0丢失。同时满足多点访问强一致性要求，业务设计更轻松
高可用：节点故障秒级完成接管，对业务影响小。即使N-1节点同时故障，实例依然可用
性能稳定：计算层分布式多线程模型，存储层RDMA高速网络拓扑，深度优化RocksDB存储引擎，冷热分离加速热点数据访问。全链路的性能设计无处不在，稳定可靠

高性价比，实现计算专用，降低存储成本

计算专用：基于GeminiDB计算存储分离架构，通过专门的计算节点，提升计算性能，降低传统组网的备份机计算资源的浪费
低内存成本：GeminiDB Redis相对开源Redis纯内存架构，对内存的容量要求更低，硬件成本下降75%~90%
低存储成本：针对时间序列类数据，GeminiDB Influx采用自适应压缩算法、自动冷热分级存储，相同数据量下存储成本仅有关系型数据库的1/10

键值数据场景

数据特征

Key-Value类型数据，以及Hash、List、Sorted Set、Set、Stream等传统Redis结构

海量数据，访问低延时

业务场景示例

广告：AI业务需要低延时、大容量的KV数据库，用于存储特征画像。同时满足媒体端对时延的高要求，适合RTA、DSP等广告业务。

游戏：存储玩家数据、活动、排行和好友等信息；支持原地指定时间点PITR回档（游戏业务刚需需求），帮助游戏业务敏捷处理数据问题。

电商：商品库存海量数据，可靠性要求高。

协议兼容

兼容 Redis 协议接口，支持主备版、集群版全生态架构

兼容 DynamoDB 接口

文档数据场景

数据特征

文档类型数据，通过类JSON格式文件保存

支持布尔、数值、字符串、日期时间、数组和对象等，以及可嵌套复合类型

高并发

数据更新频繁

业务场景示例

社交：互联网社交场景通常会产生大量的非结构化数据，比如：大量的用户信息、朋友圈信息、地理位置索引类信息（如附近的人、地点等）。

物联网：普遍有高并发需求，比如：智能设备上报的日志信息。

电商：订单信息、订单状态、物流信息会不断更新，通过JSON内嵌数组可一次将订单所有的过程读取出来，适合电商订单、收藏夹和购物车场景。

游戏：用户信息、游戏装备、会员积分等数据直接以内嵌文档的形式存储，方便查询和更新。

协议兼容

兼容MongoDB接口，支持副本集架构

宽表数据场景

数据特征

宽表模型，列字段可以灵活扩展，支持结构化/半结构化数据

PB级数据存储

业务场景示例

社交：在社交场景下，存储用户信息、关注、发帖、点赞、内容分发等，平滑的弹性扩展可急速应对社交热点的流量冲击，比如：Facebook、Discord、畅连通话等应用。

IoT：适用于 IoT 设备产生的海量数据，高并发写入。如物流、穿戴、智慧城市监控等产生的数据都可以进行高并发存储。

数据仓库：在广告、历史订单、feeds流、消息、日志、推送等海量数据的场景下，通过对平台数据库的数据再分析，形成新的用户/行为等画像。

协议兼容

兼容开源Cassandra协议接口，开发体验类似MySQL，支持集群架构

兼容开源HBase协议（公测中）

兼容DynamoDB接口，无感迁移DynamoDB

GeminiDB Cassandra 接口

时间序列数据场景

数据特征

时序数据，所有数据都带有时间戳信息

极简的数据类型：布尔、int、string、 float

海量数据写入和查询为主，很少有更新

数据流量平稳，没有明显的峰谷波动

数据都是结构化的，数据由单一的数据源生成

数据按时间保留，到期后删除

业务场景示例

车联网：汽车状态、位置、电池等状态信息。

物联网：工厂设备、终端、环境等上报的状态数据。

应用运维监控：虚拟机、容器的CPU，内存，磁盘的使用情况的监控。

商业智能：业务流水、用户行为等数据聚合计算分析。

协议兼容

兼容InfluxDB接口，支持集群架构
