MySQL on Ubuntu can be improved in a couple of things in my mind. I can consider performance-wise, scalability-wise, reliability, availability, security, and operational simplicity. Right now it is good enough for ourselves or our organization. But if it is considered from a scalability perspective, currently, MySQL on Ubuntu scales fairly well. Write scaling is hard and manual sharding is required. In that case, what we can improve is native sharding support, better distributed write handling, and easier multi-primary setups. For performance optimization, I can say currently the limitation is the required expert tuning. The default configuration is conservative. What we need to do in that is auto-tuning based on the hardware, better index recommendations, and smarter query optimization. Another point is high availability. Currently, what happens is that replication setup is complex. If you make the setup but if you want to replicate it, it will be complex. What we have to do is build in automatic failover, easier cluster setup, and faster recovery time. The fourth thing is security enhancements. Currently, whatever security is set up is manual. Misconfiguration risk is there. What we can improve in that is secure-by-default configuration and mandatory SSL in production because SSL is very important nowadays. This thing we can improve. Stronger password policy by default. For the security perspective, we can provide a stronger password policy by default. For recovery and backup simplicity, I can say that currently, we need scripting for the backups and recovery testing is a manual thing. What we can do here is built-in backup scheduler. We can run one scheduler and every day it will take the backups. If we can have it, it will be great. One-click restore and automated recovery validation. Those things we can improve. Another thing is observability and monitoring. Currently, what happens is limited built-in visibility and external tools required for that. What we can do here is provide native performance dashboard, query heat maps, and bottleneck detection. Those things we can improve. Another thing I can consider is at the Ubuntu level. Because if you consider, the OS and DB configuration is disconnected and kernel tuning is also manual. What we can improve in that is DB-aware kernel tuning, better file system defaults for the DB workloads, and pre-tuned DB server profiles. I can say cloud-native enhancements. Right now we are working on a traditional architecture and manual cloud optimization. It would be better to have Kubernetes native auto-scaling and storage-aware tuning. Those can improve my area for that. Another thing is developer experience. Debugging a query is hard. Currently, if we are running on Ubuntu and code something, there are no other tools we are using. Debugging is very hard. Also, error guidance is limited. We can say that a clearer error message, query rewrite suggestions, and schema change safety checks by default. Those kinds of improvements we can do. I can say I mostly covered the improvements needed for MySQL on Ubuntu, but one thing I can say is that there is also some limitation on the governance and compliance base. Auditing needs configuration. Some configuration we need to read. Compliance reporting also is manual right now. We can improve that with built-in audit templates, compliance-ready modes we can provide, and easier data masking we can do. Those things we can add also.
