Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
8.6
Couchbase provided a significant ROI by halving costs, improving speed-to-market, cutting expenses, and supporting higher user volumes.
Sentiment score
5.8
User experiences with MongoDB ROI vary, from significant performance boosts to uncertainty and mixed returns due to adoption challenges.
Reducing costs by half and supporting around five times the non-peak user volume during peak hours.
Couchbase maintained consistent productivity as a finished solution that worked well, saving us time dealing with something less efficient.
 

Customer Service

Sentiment score
7.3
Couchbase support is generally responsive, but experiences vary; users often resort to documentation for independent issue resolution.
Sentiment score
6.5
MongoDB's support is well-regarded for community and online resources, with paid users noting efficient but variable response times.
The support team has been helpful with VNET configuration, Sync Gateway, and other technical issues.
We used the documentation, which was well-written and clear.
 

Scalability Issues

Sentiment score
7.6
Couchbase is highly scalable, efficiently manages large data volumes, and offers flexibility with Capella's adaptable CPU and memory configurations.
Sentiment score
7.6
MongoDB is praised for high scalability, efficient data management, accommodating growth, though challenges exist with replication and heavy workloads.
It was easily scalable, which is expected from a NoSQL database.
Couchbase is extremely scalable, which is critical when handling high throughput and load.
MongoDB is highly scalable.
 

Stability Issues

Sentiment score
7.6
Couchbase is stable and reliable, with excellent uptime, though some users experience index issues addressed in updates.
Sentiment score
7.8
MongoDB is highly rated for stability, with minor issues manageable through optimizations, not impacting overall reliability assessments.
We didn't experience any downtime, and the data stayed there consistently.
Couchbase is highly stable, rated at nine out of ten.
 

Room For Improvement

Couchbase needs improvements in failover, upgrades, integration, user interface, security, memory usage, support, concurrency, and data management.
MongoDB requires better BI integration, SQL queries, security, stability, scalability, cost-efficiency, and improved documentation and training resources.
I would like Couchbase to provide more functionality via the UI, as some operations, such as time-based scaling, currently require using the API.
This delay meant that data on another database, Elasticsearch, was not always up to date, which could be noticed in the games.
While solutions for other databases like SQL or PostgreSQL already exist, MongoDB requires additional integrations for developing AI solutions.
 

Setup Cost

Couchbase provides flexible payment plans but can be costly, with integration challenges leading many to choose commercial support.
MongoDB offers affordable options compared to Oracle, with cost-effective cloud subscriptions but potentially pricier on-premises features.
It can range between 25,000 to 40,000 Euros per year depending on company requirements.
We use the free version of MongoDB, so there are no licensing costs.
 

Valuable Features

Couchbase offers exceptional scalability, ease of use, and speed, outperforming competitors in data handling, reliability, and versatility.
MongoDB offers scalability, flexibility, JSON storage, ease of use, high availability, powerful features, and strong community support for diverse applications.
The best thing about Couchbase is its versatility in handling data.
The most valuable features of Couchbase include the key-value storage due to its speed and the multi-master capability, which provides more speed and scalability compared to master-slave databases.
We didn't experience any downtime.
It offers flexibility in schema adaptation, allowing us to change the schema and add new data points.

Featured Reviews

Asad Rizvi - PeerSpot reviewer
No SQL cloud based solution used to manage unstructured data and push out large volumes of metrics at a low latency
The main advantages were associated with it being a no SQL database. It helped us send out metrics or rewards to multiple players in our game at a very low latency. I pushed a lot of updates onto the Couchbase cluster and it performed very well. I was able to cater to 50,000 people within minutes and update our Couchbase DB very easily.
Hamidul Islam - PeerSpot reviewer
Lightweight with good flexibility and very fast performance for searching data
I used the solution in the production level to search data and create education-based tutorials for a project. We had 30 managers, senior architects, tech leads, and software engineers working on the project.  Currently, I use the solution for my personal work.  The solution has good flexibility…
