Teradata excels in parallel processing, scalability, and performance, offering robust data management, security, and integration for efficient data warehousing.

Always On HADR functionality is one of the features that I use on a daily basis and one of my most used features, saving me lots of time, especially since previously I had to build a SQL cluster and Windows clusters that had many dependencies on shared infrastructure, but now with Always On, it is too stable with easy management and almost zero maintenance, which SQL Server handles itself.

Ledger and seamless integrations have strengthened trusted analytics and unified workloads

Data Warehouse Lead at Resurs Bank AB (publ.)

SQL Server's high availability and disaster recovery features work for supporting mission-critical applications, but there is much more to wish for. These features are not quite ready yet, although they do function. However, they could be significantly better. High availability and disaster recovery features should be improved in the next releases. I have noticed that everything could be improved or enhanced in the future, particularly temporal tables and window functions. Sometimes, I believe Microsoft releases features to stay ahead of competitors, but they do not make them feature-rich or feature-complete. They release something to be ahead of leaders and then seem to forget to maintain and upgrade them. I want Microsoft to pay more attention and be more mindful about the things they implement. It is fine to do a first release that works, but you cannot simply abandon it in the following years without service packs and improvements. You must continue to build on features rather than forgetting about them.
