Sentiment & Feedback
Real-world pros and cons from verified users
ScyllaDB Feedback
User sentiment analysis
- Exceptional Performance and Predictable Low Latency: Users praise its impressive performance, highlighting p99 latencies under heavy load and up to 10 times more performance compared to Cassandra due to its C++ rewrite .
- Cost Efficiency: Its performance on fewer nodes optimizes CPU use, reducing infrastructure costs while offering significant savings and operational simplicity .
- Enhanced Indexing Efficiency: The new Trie-based index format (introduced in 2026.2) improves performance for read workloads, achieving 20% to 230% higher throughput and 31% to 63% lower latency compared to legacy indexes .
- Strong Kafka Integration and Flexibility: Users appreciate its low-latency, high-throughput Kafka integration, its open-source nature, and its ability to be deployed independently, including on Kubernetes .
- Steep Learning Curve: New users often find it difficult to use initially, requiring deep knowledge of distributed systems, shard-key selection, and data modeling to avoid expensive mistakes .
- Complex Data Modeling: Designing tables for high-performance workloads can be complex, and the shard-per-core architecture requires tuning that is unfamiliar to new team members .
- Smaller Community and Ecosystem: While growing, the community is smaller than that of established databases like PostgreSQL, and monitoring integration and developer SDKs lag behind competitors like Cassandra .

User sentiment analysis
- Serverless, fully-managed vector database with built-in RAG (Retrieval-Augmented Generation) pipeline – handles ingestion, chunking, embedding generation, and summarization without custom infrastructure.
- Hybrid search combining sparse (BM25) and dense (vector) retrieval with learned sparse models, delivering higher relevance accuracy than pure vector search.
- Native hallucination detection and grounded generation metrics, providing confidence scores on LLM outputs to reduce inaccurate responses.
- Zero-ETL approach – ingests documents directly from cloud storage (S3, Google Drive) and websites, automatically performing extraction and indexing.
- API-first design with gRPC and REST endpoints, offering low-latency queries (<100ms) at scale with automatic sharding and replication.
- Closed-source, proprietary format leads to significant vendor lock-in; migrating indexed data and embeddings to another platform requires full re-ingestion and recomputation.
- Cost model is token-based and can spike unpredictably for high-volume ingestion or summarization queries, making budget forecasting difficult.
- Limited customization of embedding models – you must use Vectara's proprietary embedding and summarization models; fine-tuning or BYO-LLM is not supported.
- No on-premise deployment option; data sovereignty requirements force reliance on cloud regions, which may not satisfy strict regulatory mandates.
