Why teams choose Sirin
-
Smart data management
- Automatic Zstd compression at the page level.
- True in-memory tables — all data lives in memory, not just the write-ahead buffer.
- Picodata's LSM-tree — compact metadata storage and prompt automatic cleanup. REPAIR is no longer needed.
-
Distributed query execution
- A unified data space — all nodes see the full schema and data.
- Zero-token-style nodes thanks to the tier architecture.
- Efficient consistent secondary indexes.
-
Production-ready for the critical perimeter
- FSTEC trust level 4 certification.
- Tested on industrial MES/IIoT workloads.
- Horizontal scaling with built-in fault tolerance.
-
Extreme performance
- Strong consistency by default — no trade-off between speed and reliability.
- Lightweight transactions (LWT) faster than Cassandra thanks to Raft instead of Paxos.
- Resident storage — response time tens of times lower than Cassandra.
