Valuable Features

ScyllaDB's key features include lightweight infrastructure requirements and user-defined types for data consistency. Its performance excels in speed and efficiency. It allows seamless integration with Cassandra SDK and migration from DynamoDB. High availability, partitioning, and excellent failover systems enhance reliability. Fine-tuning capabilities enable efficient table structures and data synchronization. Innovative I/O optimization supports distributed systems, maintaining speed under heavy data loads. Encryption and API support simplify use and scaling across regions.
  • "Scalability in performance is good."
  • "The performance and scalability are good, and we hardly see any major issues with ScyllaDB."
  • "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 systemsand 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."

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.
  • "Support and the availability of support need improvement. I would give them a six out of ten."
  • "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."

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.
  • Cloud - Fully-managed database-as-a-service. Includes all Enterprise features in a serverless platform.
  • "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."
