Efficiently handles high-traffic scenarios and compatible with PostgreSQL extensions, offering flexibility in database management
There are many areas of improvement , especially in terms of DDL query routing. Even though it's masterless, DDL queries need to be sent to the coordinator node. Also, setting up a multi-node environment could be more straightforward. Currently, setting up a multi-node environment is challenging. It's a bit tricky. Installation on each PostgreSQL node can lead to communication issues between nodes. An automatic rebalancing feature would be a significant improvement. Currently, I have to manually command the rebalance. It would be more convenient if it was rebalanced automatically. The dashboard and monitoring capabilities are good, but it would be helpful to have an integrated availability dashboard.

Data platform has transformed analytics and now provides seamless storage and insight on user behavior
Microsoft Azure HorizonDB scales perfectly. It automatically scales whenever there is a load on the application. I have configured the deployment files on my projects, and the database is able to handle automatic scaling by itself, so I do not have to put much attention on that aspect. It scales down automatically as well. I monitored the scaling and scaling out one or two times during the initial stage when I was first including this database in my project. After the first and second times, I checked only the logs for automatic scaling and scaling out. I have not encountered any issue on the scaling side, and it provides consistent performance for both scaling and scaling out.
