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.

Quotes from Members

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

Pros

"I am getting much better performance than relational databases."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"The time series data was one of the best features along with auto publishing."
"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."
"The technical evaluation is very good."
"Its analytics has enabled Pythian's clients to get the business insights as quick as they wanted. Its lower maintenance has also improved the ROI."
"I appreciate the flexibility offered by Vertica's projections. It allows for modifying the primary projection without altering the tables, which helps to optimize queries without the need to modify the underlying data."
"Initiate on one node, and the RPM propagates automatically to all other nodes. ​"
"It's the fastest database I have ever tested. That's the most important feature of Vertica."
"Vertica's most outstanding features are the compression rates achieved and the speed of access of high volume data."
"Speed and resiliency are probably the best parts of this product."
"The hardware usage and speed has been the most valuable feature of this solution. It is very fast and has saved us a lot of money."
"Eighty percent of the ETL operations have improved since implementing this solution."
 

Cons

"Batching bulk data can cause performance issues."
"Fine-tuning was a bit of a challenge."
"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."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"It can be difficult to analyze what's going on inside of the database relative to other databases. It can also be difficult to troubleshoot sometimes."
"The initial setup of Cassandra can be difficult in the configuration. There might be a need to have assistance. The implementation process can six months for connecting to certain databases."
"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."
"The disc space is lacking. You need to free it up as you are working."
"Vertica's native cloud support could be improved, and its installation could be made easier."
"The geospatial functionality could be designed better."
"Pricing could be more competitive."
"They could improve on customer service."
"In our company, we have faced difficulties in scaling the solution for certain use cases."
"Performance of management of metadata layer (database catalog) needs improvement. We still have to have smaller customers on PostgreSQL; Vertica cannot manage thousands of schemata."
"Metadata for database files scale okay, but metadata related to tables/columns/sequences must be stored on all nodes."
"The integration with AI has room for improvement."
 

Pricing and Cost Advice

"I use the tool's open-source version."
"We are using the open-source version of Cassandra, the solution is free."
"We pay for a license."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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."
"It is fast to purchase through the AWS Marketplace."
"The price is reasonable. We use a pay per license model. Firstly, you need to buy a license. After that, you mainly pay the annual support fee of around 20% or 25%. I think their prices are quite reasonable."
"The pricing for this solution is very reasonable compared to other vendors."
"From a cost perspective, the software is less than most of its competitors."
"The pricing could improve, it is a little expensive."
"The price could be cheaper and it is best to negotiate the price."
"Start with license per 1TB. Starting from hundreds of TB there is unlimited licensing to be considered. Move historical data to HDFS/S3 which are significantly cheaper or even free."
"The price of Vertica is less expensive than some competitors, such as Teradata."
