Room For Improvement

CockroachDB requires improvements in documentation, compatibility, UI features, disaster recovery, latency optimization, integration, and cost efficiency for global deployment.
MongoDB Atlas faces challenges in cost management, configuration, UI stability, performance, integration, support, security, and containerization.
For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking.

MongoDB Atlas should support containerization.
General Manager at Kaleyra
Enhancing capabilities for data pipelines and visualization dashboards.
DB Architect / Consultant at Virtusa Global
The UI is good, although I have checked one aspect in MongoDB Atlas: when we make transactions, they do not process in real-time and require a refresh.

Manager, Software Engineering at a tech vendor with 10,001+ employees
Provides developer-friendly environment with robust security and cost-efficiency
The platform should provide a UI feature where users have the ability to manage it. The CockroachDB platform should have a chatbot where users can inquire about pricing or seek solutions for queries, rather than relying on email support. The current UI only provides SQL playground, which is technical. There should be a UI playground where users with limited technical knowledge can run and update queries, similar to phpMyAdmin or Adminer. Latency optimization could be improved for globally distributed applications, particularly in query routing. For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking. The disadvantages include cost-efficiency with multi-region deployment and schema migration speed, which should be faster compared to other drivers. The query optimizer should handle complex queries better through the UI interface.
Lintz Veloso - PeerSpot reviewer
IT Manager at a government with 11-50 employees
Developers have benefited from flexibility and performance but pricing has needed further attention
I am only familiar with databases and applications. I am from the development team and I am a user of database and cloud but I don't know the infrastructure. As a user, I deal with the Oracle Database. I know the organization has a license with the product. We don't utilize real-time analytics with MongoDB Atlas. I don't use MongoDB Atlas directly, so I don't know how it can be improved. I would place MongoDB Atlas at a medium level. I would rate it at a six or seven. I believe MongoDB Atlas can improve a little. My overall review rating for this product is six out of ten.
