Well-equipped to handle a massive influx of data and billions of requests
The use of Cassandra in real-time data analytics has been pivotal for our e-commerce platform. As our platform operates 24/7, providing services to sellers and customers alike, the need for real-time updates is paramount. For instance, when a customer leaves comments or feedback on an image, they anticipate an immediate reflection of these changes on the portal. Similarly, sellers altering product attributes or updating images expect instant visibility of these modifications. Handling large data volumes with Cassandra has been an excellent experience. Despite challenges related to the influx, these were not attributed to Cassandra itself but rather to middle-layer issues. Generally, it demonstrated scalability with workloads, thanks to its horizontal scaling capabilities. We could easily add new nodes to the system as needed, ensuring the platform coped well with increasing loads. The tool's most beneficial feature for scalability is its entire architecture. The absence of a single point of failure or a leader within the ecosystem contributes to its robust scalability. This key aspect influenced our decision to opt for the Cassandra ecosystem. In terms of performance, it demonstrated the ability to handle approximately 1.6 billion requests per day. This was achieved on AWS using EC2 instances, and it was during a period about four to five years ago.

Supports multiple data models and offers AI capabilities
With some of the operations, we used to face some challenges with scalability. Although it worked pretty well, in some scenarios, we noticed issues where the replications and the sharding were not happening correctly. In recent versions, we also faced some issues in terms of enabling advanced operations like FTS and vectors. Although it works pretty well, in some places, we do face challenges, especially on a heavy scale. I think all issues are being addressed in the latest version of Couchbase. The resources are not that good for Couchbase. The tool's documentation is pretty extensive, but if you go for any kind of courses or tutorials, there are very limited resources available. It also becomes a little bit challenging for new people to get onboard into it. MongoDB and other such open-source database tools perform really well as they're really widely adopted, and they have resources available to get you onboarded pretty quickly. I think that we do face some challenges with Couchbase, but luckily, we have the tool's enterprise version solution, so we get all the support from the product team.

Transforms data flow with adaptable schema and smooth public cloud deployment
One of our business units uses MongoDB, and we developed an ETL pipeline that extracts data from MongoDB and transfers it into our data warehouse MongoDB is a NoSQL database that is similar to a document database. It offers flexibility in schema adaptation, allowing us to change the schema and…

Pros

"Since I haven't had years of experience with it, it's still new to me. One valuable feature is its distribution, so I can run it partly in the cloud and part on-prem. That's a feature I'd like to use but haven't yet because we're trying to move to Azure. I don't know if or when that will happen. Ideally, we'd have it distributed over the cloud and on-prem simultaneously, so if something happens to our on-prem, we can keep going in the cloud, like a pay-as-you-go model with Azure."
"The technical evaluation is very good."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"The use of Cassandra in real-time data analytics has been pivotal for our e-commerce platform. As our platform operates 24/7, providing services to sellers and customers alike, the need for real-time updates is paramount."
"Cassandra has some features that are more useful for specific use cases where you have time series where you have huge amounts of writes. That should be quick, but not specifically the reads. We needed to have quicker reads and writes and this is why we are using Cassandra right now."
"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."
"I am satisfied with the performance."
"I have found the views to be very valuable."
"The most valuable features are the ease of application and the merging of data."
"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."
"Investing in Couchbase has significantly lowered our operational costs and increased throughput, reducing costs by half and supporting around five times the non-peak user volume during peak hours."
"The best thing about Couchbase is its versatility in handling data."
"Couchbase has not given any performance problems as of now."
"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."
"The whole stack is valuable, but the portion of the stack that we're finding really handy is the analytics engine because that allows us to take and pre-build views."
"MongoDB is scalable and stable. The initial setup is very easy, and deployment and maintenance can be done by one person."
"MongoDB is relatively fast compared to relational databases."
"I found that MongoDB is most valuable for storing school-related queries. It's also user-friendly, and I found no difficulty accessing it. Setting it up is easy too."
"Sharding is an excellent feature of MongoDB."
"The most valuable feature is the speed of MongoDB."
"MongoDB's best features are scalability, document management, and data security."
"MongoDB has many good replication features and good performance."
"It is easy to set up."
 

Cons

"Doesn't support a solution that can give aggregation."
"There were challenges with the query language and the development interface. The query language, in particular, could be improved for better optimization. These challenges were encountered while using the Java SDK."
"There could be more integration, and it could be more user-friendly."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"Cassandra could be more user-friendly like MongoDB."
"Fine-tuning was a bit of a challenge."
"While Cassandra can handle NoSQL, I think there should be more flexibility for whole schema design when data is stored in wide columns. Additionally, I believe that eventual consistency should be enhanced."
"I want Cassandra to update its open-source version more quickly. It's already feature-rich, but I'd appreciate better integration with other NoSQL databases like MariaDB or MongoDB. If I ever need to work with customers or vendors using different NoSQL databases, having native integration in Cassandra would make managing and interacting with their databases much easier."
"I would like Couchbase to provide more functionality via the UI, as some operations, such as time-based scaling, currently require using the API."
"I would like Couchbase to provide more functionality via the UI, as some operations, such as time-based scaling, currently require using the API."
"Although it worked pretty well, in some scenarios, we noticed issues where the replications and the sharding were not happening correctly."
"The platform's grouping features need improvement."
"What is missing is that they have a new version, Couchbase Mobile three, but they haven't really updated or provided help or documentation about what needs to change to update to the latest mobile version."
"I have tried multiple libraries in a demo they provide and it works fine, but when it merges with libraries, it creates a problem."
"There are some limitations to the database. The SQL database cannot handle real-time processing for critical IoT scenarios. What we have to do is store our data into the database then code it out, this wastes a lot of time."
"The main problem has been with integration with the services."
"Sometimes, the tool goes down temporarily. There are some stability issues in the product."
"I think it would be good to have more search options such as an index resource. This will provide more options and resources to do advance searches."
"The improvements could be made to intelligence to detect disk storage and prevent MongoDB from crashing."
"There was a need for integrating relational database capabilities, however, MongoDB has introduced a relational converter that allows conversion between SQL and NoSQL."
"MongoDB should be more stable, and support should be more efficient."
"MongoDB could be more secure."
"We find it difficult to incorporate MongoDB in some projects."
"The auto transaction feature is something that I found a little bit problematic. If we want to run two or three transactions at a time, we get write conflicts. So, it becomes really difficult when concurrency comes into the picture."
 

Pricing and Cost Advice

"We pay for a license."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"I use the tool's open-source version."
"I don't have the specific numbers on pricing, but it was fairly priced."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"We are using the open-source version of Cassandra, the solution is free."
"The licensing cost of Couchbase is quite expensive compared to other databases."
"It can range between 25,000 to 40,000 Euros per year depending on company requirements."
"I would rate this solution a nine out of ten for pricing as it is affordable."
"We estimate that it's not very expensive, however, the pricing that you can get from the account managers, e.g. the public pricing, could be a bit expensive."
"I wouldn't say Couchbase offers good value for money."
"It seems very reasonable. It's a lot cheaper than Redis, but we've got an enterprise license. So, it's about normal. It's not outrageous in price as far as we've seen. From Couchbase, there's no additional fee as far as I'm aware, but when you're integrating, there's an additional fee because a lot of times, they don't have an integration stack."
"The price of this solution is better than some of the other competitors."
"At the moment, all customers are using the community version."
"I believe that MongoDB is free."
"MongoDB is a bit expensive compared to its competitors."
"MongoDB is an open-source product."
"Our customers pay for yearly licenses for MongoDB."
"We are using the Community Edition of MongoDB."
"The pricing is normal. Price-wise, the product is not too much expensive."
"There is an annual subscription for the use of this solution."
