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.

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.

When it comes to the performance, it's not as good compared to MongoDB or Postgres. However, performance is not a big issue in ScyllaDB. If you have a very large scale of data, it takes at least five milliseconds more time to execute the query compared to MongoDB or Postgres. This is the little drawback in ScyllaDB. But on the safer side for CDC, read and write, and all things are good in ScyllaDB. There are some extra packages we can apply on ScyllaDB separately. We can add some extra layers on top of ScyllaDB to improve the performance. So, it can improve throughput, latency, scalability, and performance. The documentation is not well established for new developers. If a developer is starting their career, it's not ready to use. MongoDB and other things are very scalable and everything is documented. But here, everything is not documented. You have to go to the GitHub repo, Stack Overflow, or Google things. The documentation is not well maintained. But if a developer is experienced, like two or three years in MongoDB, they can make the wrapper cluster and use ScyllaDB easily. If anyone is pressured, it takes some time to adjust to ScyllaDB because the scalability and performance on the internet are not well improved, and the documentation is not well written or maintained.

"I like how fast it is to query data from the ScyllaDB node!"

Room for Improvement

ScyllaDB users highlight several areas needing improvement: better documentation and support, efficient management of deletions, and improved data modeling and scalability. Users mention complexities in setup and integration, compatibility issues, and communication in transactions. Performance is seen as suboptimal compared to alternatives like MongoDB or Postgres, especially in large-scale data handling. There are also concerns about the sales promises not aligning with actual ROI and compaction benefits. Additional features and faster support response are desired.

"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."
"Some of the regular commands in NoSQL do not work."

Pricing

ScyllaDB offers a free basic option, a more advanced self-managed enterprise option, and a fully managed cloud database option - providing flexible NoSQL database solutions for different needs and scales.

Open Source - Free version with basic features like clustering, replication, Cassandra compatibility, lightweight transactions, role-based access control, change data capture, secondary indexes, and materialized views. Automation for recurrent tasks, such as backups and repairs limited to 5 nodes.
Enterprise - Adds advanced features like workload prioritization, incremental compaction, encryption, auditing, and authentication. Also includes dedicated community support, long-term release support, 24/7 critical issue hot fixes.

"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."
"It's a bit expensive."
"It's free."
