Think about if you are in a different geographic location and your cluster is hosted in two different geographic locations, maybe one in South Pacific and one in Western Europe. In both cases, if write transactions are happening, this is a good way to basically order the transactions so that the eventual data consistency is there.

Performance tests have been streamlined for analysis while query tuning still needs improvement
The technical support or community support for MariaDB on CentOS is bad. There is a main problem with all the companies that sell this kind of tool and services. The first level of support is the first one you reach. When you begin to have a more difficult problem, there is no one available because sometimes you need to update the call and recall on it. This is not good because when we have some big problem on the database, we need to have a database administrator, not a person who reads instructions on the screen. It is always the same problem. My rating is two.
MG
CEO at Grant Corporation
Consistent use of flexible data and solid transactions has reduced costs and simplified projects
PostgreSQL on Ubuntu could be improved with easier out-of-the-box configuration. The default settings for PostgreSQL on a fresh Ubuntu install are very conservative. Things such as shared buffers and work memory are too low for any real production workloads, and you have to know how to go in and tune it manually. A smart default configuration wizard during installation that detects hardware and suggests settings would save a lot of junior developers from performance headaches. That is important. Built-in connection pooling is another area; PostgreSQL does not handle large numbers of concurrent connections well natively. You end up needing to set up PG Bouncer separately, which is another tool to learn, configure, and maintain. Having a lightweight connection pooler built into the core installation would be a real quality-of-life improvement. Additionally, a better built-in monitoring UI would help. Primarily, if you are working with Ubuntu, you are largely working with PostgreSQL on the command line and installing third-party tools such as pgAdmin or Adminer. A lightweight built-in web dashboard for basic health monitoring would improve projects significantly. Finally, upgrades between major versions and smaller versions should be a lot easier as well. None of these are deal-breakers; they are just nice to have improvements.
