I like Teradata Vantage for its performance and scale. Its massively parallel processing architecture distributes queries across thousands of nodes simultaneously, making it perfect for petabyte-scale data without performance degradation. The major optimizer is perfect, and I appreciate the workload management and qualified calls. Hybrid cloud flexibility and high concurrence are also standout features, along with its rock-solid reliability and built-in data protection. Review collected by and hosted on G2.com.

The cost is really the biggest barrier by far. Licensing is enterprise-level expensive, and the pricing model isn't transparent. The UI/UX also could be improved. The setup and administration, the cloud-native field, and the developer experience as well could be better. The initial setup was really not that easy and it requires specialized DBAs for on-prem deployment. Vantage on cloud is easier, but it's not that simple. Review collected by and hosted on G2.com.
