Customer Service

Sentiment score
6.0
CockroachDB customer service is mixed; technical support quality varies, with users praising the AI chatbot, but responsiveness needs improvement.
Sentiment score
6.8

The issue was resolved efficiently.
Manager, Software Engineering at a tech vendor with 10,001+ employees
I have used them sometimes, even recently, and found the feedback to be spot on our needs.
Partner at Red software systems
The features of MongoDB Atlas fall short, resulting in an average rating due to higher-expectation features still lacking in its offerings.
DB Architect / Consultant at Virtusa Global
Most of the issues I encountered, like query performance or indexing, were handled internally through monitoring, optimization, and best practices.
Senior Software Developer at NIT
 

Scalability Issues

Sentiment score
7.0
CockroachDB excels in scalability and resource management, praised for seamless scaling from small to large, supporting diverse needs efficiently.
Sentiment score
7.6
MongoDB Atlas is highly scalable, adapting to changing demands, efficiently distributing data, and facilitating seamless expansion for applications.
It's very much scalable, and I would rate scalability a nine.
General Manager at Kaleyra
It supports both vertical scaling and horizontal scaling through sharding, where data is distributed across multiple nodes.
Senior Software Developer at NIT
MongoDB Atlas offers sharding as a scalability feature, although it does not perform as well as Oracle.
DB Architect / Consultant at Virtusa Global
 

Stability Issues

Sentiment score
6.6
CockroachDB is stable overall, highly rated for reliability but faces challenges with protocol issues and large, complex workloads.
Sentiment score
8.0
Users commend MongoDB Atlas for stability and reliability, despite interface critiques and challenges with OLTP transactions and triggers.
Since it is a managed service, features like replication, automatic failover, and backups are handled by the platform.
Senior Software Developer at NIT
When it comes to OLTP transactions, its performance declines.
DB Architect / Consultant at Virtusa Global
The stability of the product is very high.
General Manager at Kaleyra
 

Room For Improvement

CockroachDB requires improvements in documentation, compatibility, UI features, disaster recovery, latency optimization, integration, and cost efficiency for global deployment.
Users seek MongoDB Atlas enhancements in data processes, integration, UI, performance, scalability, documentation, and cost efficiency.
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.
Manager, Software Engineering at a tech vendor with 10,001+ employees
Enhancing capabilities for data pipelines and visualization dashboards.
DB Architect / Consultant at Virtusa Global
MongoDB Atlas should support containerization.
General Manager at Kaleyra
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.
Software Developer at Styx Global
 

Setup Cost

Enterprise users find CockroachDB affordable and reliable, with flexible pricing options appealing despite some perceiving high costs.
Enterprise buyers find MongoDB Atlas competitively priced, valuing its pay-as-you-go model, flexibility, and minimal initial setup expense.
For our service, it was around 300 to 600 euros per month, which was acceptable for our customers.
Partner at Red software systems
The price of MongoDB Atlas is reasonable, which is why many organizations, including mine, are opting for it.
DB Architect / Consultant at Virtusa Global
 

Valuable Features

CockroachDB provides easy setup, fault tolerance, scalability, and security, while supporting PostgreSQL compatibility for optimal performance across regions.
MongoDB Atlas excels in scalability, security, usability, and efficiency, effectively handling unstructured data and reducing operational costs.
CockroachDB's geo-distribution feature is superior to traditional databases.
Manager, Software Engineering at a tech vendor with 10,001+ employees
MongoDB Atlas is a fully managed service, meaning it handles deployment, scaling, backup, patching, and maintenance automatically, which allows developers to focus more on application logic instead of infrastructure.
Senior Software Developer at NIT
I find MongoDB Atlas highly scalable and easy to use, with very good support.
Partner at Red software systems
It is particularly useful for unstructured and semi-structured data because of its performance in these areas.
DB Architect / Consultant at Virtusa Global

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.

Flexible document workflows have accelerated schema changes and simplified evolving data models
MongoDB Atlas currently has almost all the features we require, but there are some points where I see certain improvements. One area is cost visibility and optimization. Since pricing is largely based on storage and cluster size, it can sometimes be difficult to predict or optimize cost without deeper insights. More granular cost breakdowns or recommendations would be helpful. Another area I can mention is performance tuning transparency. While MongoDB Atlas provides monitoring and suggestions, debugging deeper issues like slow queries, index efficiency, or shard imbalance can sometimes require more control or visibility. Cost optimization, deeper performance insight, and easier scaling decisions would make MongoDB Atlas even more powerful. A couple of additional areas where MongoDB Atlas could improve are integrations and developer experience. For integrations, while MongoDB Atlas supports major cloud providers and tools, deeper and more seamless integration with observability patterns would make troubleshooting distributed systems easier. On the documentation side, while it is generally good, some advanced topics like sharding strategies, performance tuning, and real-world scaling patterns could benefit from more practical guidance. Additionally, a better local-to-cloud development experience, making it easier to replicate production-like MongoDB Atlas environments locally, would help developers test performance and scaling scenarios more efficiently.
