SingleStoreDB is a high-performance, distributed SQL database designed to power real-time applications. It offers ultra-fast ingestion, millisecond-level response time for OLTP queries and sub-second latency for analytical queries on historical data. SingleStoreDB eliminates the need for multiple purpose-built data engines with its distributed architecture and patented universal storage engine. This allows support for both transactional and analytical workloads, as well as diverse datasets, including relational, key-value, JSON, and vector. By sharding tables, using Universal Storage and rowstore tables, and creating various indexes such as hash indexes and column group indexes, SingleStoreDB can improve query performance and support mission-critical applications. The database also uses partitioning strategies to optimize query processing and offers a wide range of features for enterprise data engineers and SaaS application developers.
