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…

Self-hosting complexity and the way ScyllaDB counts operations can be confusing and may not reflect actual usage
It seems we have better options available. So probably don't go for ScyllaDB. The reason is, first, it's very high. It's not as straightforward as, like, Postgres or ClickHouse to set up. It requires a complex setup. The other problem is what they call. For example, they will say that for up to a million operations, you experience this. But the problem is if they have nine servers, then your one operation is counted as nine operations, not one. So, even though you have one write, they count it as nine. It's like it's just not false premises. You can always host it yourself, but then it's way more complex. The benefits are not substantially more than those of other databases. It's not that it's slow or anything. It's good enough and all. But it's just that ClickHouse or other databases are simpler and faster and probably provide more features. So, I kind of burn out from the database, and that's why I would keep it small.

Quotes from Members

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

Pros

"MongoDB has a simple data-loading interface."
"The initial setup isn't really that complex."
"Easier to maintain the data with its document-based storage."
"My impression is that the initial setup is straightforward."
"MongoDB is scalable and stable. The initial setup is very easy, and deployment and maintenance can be done by one person."
"The most valuable feature of MongoDB is the ease of connections, aggregation, and queries."
"We decided to work with MongoDB as its interface is easier to understand and more universal."
"The most valuable feature is the speed of MongoDB."
"The product's most valuable features are efficiency and reliability."
"The documentation is good. It integrates easily with our existing data infrastructure."
"The database is easy to use, fast, and accessible for applications because the API is straightforward."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"It is lightweight, and it requires less infrastructure."
"I like how fast it is to query data from the ScyllaDB node!"
"ScyllaDB is very fast, and I can use it for so many things."
"The best features of ScyllaDB are how it synchronizes data and its failover system. There's a unique formula to decide the number of nodes you need and the minimum required, which I find helpful. It also offers encryption and supports APIs, making it great for distributed systems and scaling databases across different regions. While it's easy to use, having prior experience helps configure it properly. There are many configurations; if you don't understand them, you might mess up the design. So, understanding your system's needs, like whether it requires more read or write operations, is crucial for setting up the correct configuration."
 

Cons

"There is room for improvement in integrating MongoDB with agentive AI solutions."
"I'd like to see an ID generator. It's very technical but I don't think it has one, so we have to go to great lengths to work around that."
"The product's data consistency could be more efficient than traditional SQLs."
"The stability could be better."
"I have found the solution difficult to operate as an administrator."
"Lacks sufficient scalability and elasticity."
"There is a need for improvement in MongoDB's customer support."
"There was a need for integrating relational database capabilities, however, MongoDB has introduced a relational converter that allows conversion between SQL and NoSQL."
"It seems we have better options available. So probably don't go for ScyllaDB. The reason is, first, it's very high. It's not as straightforward as, like, Postgres or ClickHouse to set up. It requires a complex setup."
"If you don't have the best computing resources, then it's not easy to set up. In such cases, we have to run ScyllaDB in developer mode."
"Data export, along with how we can purchase the data periodically, needs to be improved so that the storage is within control. Then, we could optimize it even better."
"Some of the regular commands in NoSQL do not work."
"ScyllaDB needs to improve its handling of transactions."
"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."
"We faced several challenges while integrating ScyllaDB into our AWS environment. One common issue was that a security port wasn’t opened on one node, preventingdata synchronization across clusters. We noticed the data wasn’t syncing correctly when we saw different record counts in other regions. After investigating, we found that the port was closed in one AWS region. Once we opened the port, the data synchronization across all nodes resumed as expected."
"The product needs to add more features and improve the response time of the support team."
 

Pricing and Cost Advice

"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"It's a community edition, so we do not pay anything."
"The product is affordable."
"We are using the Community Edition of MongoDB."
"The solution is open source so is free."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"The pricing is favorable if you opt to install MongoDB on an Amazon EC2 instance as you won't have to pay for the extra Atlas services and can instead manage the scaling yourself. This allows for a cost-effective solution and using MongoDB on a small scale, I have been able to utilize it for free."
"I chose MongoDB because it is cost-effective compared to Oracle, which can be expensive. In addition, MongoDB has good performance and has not caused any issues while working with it. It has been a good choice for me."
"It's a bit expensive."
"It's free."
"The paid version of ScyllaDB is not that expensive. The main advantage of the paid version is direct support from the ScyllaDB team, which can resolve issues faster—typically within a day, compared to two to three days with the free version. The paid version also offers better guidance and support, while the free version has good documentation and is more high-level. I’d rate their support team nine out of ten because of the quick responses from their community."
"I believe that there is a yearly licensing cost and that it's expensive."
"It is an expensive tool compared to its competitor."
