Four demos show openGauss core competitiveness

openGauss insists on improving its technical competitiveness in four aspects: high performance, high reliability, high security and high intelligence. At the same time, it continues to invest in the intelligent construction of databases, and launches the intelligent autonomous service DBMind and the third-generation intelligent optimizer ABO to realize the upgrade of optimizer technology , to solve the pain points of traditional CBO/RBO in cardinality estimation and plan selection, the complex query plan is better, and the performance is improved by more than 30%. 

Demo 1: Smart plan adaptive selection, plan execution performance

Using intelligent plan selection technology, the performance of caching plans in skewed data scenarios is improved by more than 1x

Demo 2: Second-level flashback of data

Quick query and recovery of misoperation data

Demo 3: Smart load analysis

Use intelligent SQL diagnosis algorithm to improve operation and maintenance diagnosis efficiency by 10x

Demo 4: Mandatory access control and full-stack national secret capability

openGauss provides full-stack national secret support for the entire life cycle of data transmission, computing, and storage to protect user data

Five major demos show openGauss architecture innovation

Focusing on the integration of diverse computing power, improving resource utilization, and enabling multi-mode and multi-state, create a resource pool and plug-in architecture to meet the demands of more scenarios in thousands of industries. openGauss insists on being driven by user scenarios, and continues to innovate in architecture. Focusing on user needs and pain points such as multi-mode and multi-state, intelligent operation and maintenance, openGauss launched the DataPod+DataKit combination to create a new data base.

Demo 5: Resource pooling transparent multi-write

Resource pool architecture, the standby node supports automatic forwarding of write requests within transactions to the primary node, realizing multi-write transparency in the cluster

Demo 6: Realize database native cache acceleration based on MOT

基于存储过程动态编译技术，使用openGauss的MOT作为数据库原生缓存，加速用户业务的读写操作

Demo 7：基于Wasm构建安全高效的执行引擎

多个Demo展示openGauss周边创新力

openGauss社区伙伴中国联通、粤港澳大湾区国创中心在本次大会不仅分享了基于openGauss的行业联合创新成果，还分别现场展示了其成果内容。此外，openGauss社区基础设施团队也一直致力于openGauss社区周边配套设施的服务、升级，本次也带来其最新成果展示。

Demo 10：MySQL协议兼容

通过多协议兼容的方式，让mysql客户端和sdk驱动可以无感访问opengauss，进行平滑的mysql替换

Demo 11：工业嵌入式数据库

基于openGauss内核，构筑多模态、高性能、轻量化的工业嵌入式数据库，助力工业数字化腾飞

Demo 12：智能对答机器人

openGauss小智是基于openGauss知识库训练的一款智能问答机器人，目前提供问题提示、回答、意见反馈等功能，目前还在不断优化中。
