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…

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

"The reports are useful for controlling the load of our whole architecture."
"The most valuable features of MongoDB are the variety of translations available and the ability to deploy it on the cloud is useful. The cloud users can access the data, work on the data, and if they want to import or manipulate some data they can."
"The aggregation framework is really good, allowing a developer to build very complex queries."
"MongoDB is simpler to learn and implement than traditional SQL solutions like MySQL."
"The clustering is very good. It allows us to have high availability."
"MongoDB is extremely developer-friendly because when you are starting, there is very little time needed upfront in terms of planning."
"It's easy to use."
"MongoDB is fast and efficient."
"The performance and scalability are good, and we hardly see any major issues with ScyllaDB."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"ScyllaDB is fast and reliable. It has good performance."
"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."
"ScyllaDB allows fine-tuning of the table structure. Speed is probably the most critical factor because we perform a lot of heavy data ingestion. One of its core features is its ability to handle high volumes and maintain speed when accessing data. Additionally, high availability and partitioning are built-in features of ScyllaDB."
"It is lightweight, and it requires less infrastructure."
"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."
 

Cons

"We'd like technical support to respond faster to queries."
"I have found the solution difficult to operate as an administrator."
"MongoDB can improve large-size video or media frame operations. There are a lot of customers who want to upload media frames and video games but there is some difficulty. In MongoDB, we are looking out for solutions that are for large-size media files that can be saved and navigated efficiently."
"The transaction could use improvement. From MySQL, for example, you cannot create a transaction if you are reading and writing a document at the same time."
"The solution could include more integrations with other platforms."
"MongoDB should support TypeScript."
"From my point of view, they need a totally free IDE to work at high levels."
"The performance could be faster."
"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 documentation is not well established for new developers."
"The documentation of Scylla is an area with shortcomings and needs to be improved."
"The product needs to add more features and improve the response time of the support team."
"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."
"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."
"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."
"ScyllaDB needs to improve its handling of transactions."
 

Pricing and Cost Advice

"The product is affordable."
"You only have to pay for the paid version, not the open-source version."
"MongoDB is a free solution. We wanted to have high availability and the subscription cost was quite expensive because the basic one is free and then when you want to have some other replications or other features you will need to pay money. Overall the solution is expensive."
"Our customers pay for yearly licenses for MongoDB."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"The solution is open source so is free."
"If you want support with the solution you will need to purchase a license and not use the open-source version. The license is a little expensive."
"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's a bit expensive."
"It's free."
"It is an expensive tool compared to its competitor."
