The library code of the Linux kernel contains numerous fundamental data structures and algorithms, mostly located in the lib/ directory. These have been refined by many skilled developers, resulting in highly efficient implementations. However, further optimization possibilities remain. This talk introduces how data structures and algorithms used in the Linux kernel are implemented, along with recent optimization contributions made to the Linux kernel.

This session will show you the features from an Ultimate acceleration InnoDB sub-engine - Heatwave, and how it works with Grafana aggregates hundreds millions of rows in seconds to create a real time dashboard, this session also show you how to show the details of how MySQL handles these queries on Grafana

1. A brief introduction to the origin of RT-Thread, as well as its application scenarios and cases;
2. RT-Thread ecosystem construction and what it has done in open source;
3. What has RT-Thread done to guarantee the security of the open-source;  
4. Some Latest updates in RT-Thread, eg. The release of its open-source Micro-Kernel Operating System.

The holy grail of Cloud Native tech is to have zero vendor lock-in. Container makes everything easier. But even with the easiest platform, sometimes you still need to run into problems. In this talk, Phil will share the knowledge about how to diagnose and troubleshoot container (podman, docker) and container platform (Kubernetes, OpenShift).

Does your database need to 99.999% high availability? Is it possible to linearly scale database capacity and throughput to accommodating the surge number of user?

Does your database need to reply queries in microseconds consistently event it is in peak time?

This session will share you the benefits, disadvantages and possible pitfalls of various with MySQL High Availability solutions (including shared storage plus Clusterware, Master-slave replication, Group Replication, and DB Cluster) and how to avoid the pitfall. I also will concludes my experience from several MySQL implementation projects, hope you may learn how to apply the right solutions for your applications and how to make the best from those solutions.

We started a smart farming group in 2017, and developed tools with loT, data analysis, computer vision, and robot technology. It can help farmers to monitor and optimize the food production.
