Referential Integrity Checks in SingleStore

SingleStore is a real-time data platform that provides powerful operational and transactional capabilities for intelligent applications and analytics, with its patented Universal Storage engine offering ultra-low latency and high concurrency for real-time ingestion and querying of data. The platform's hybrid transactional-analytical processing (HTAP) capabilities enable seamless integration of transactional and analytical workloads, allowing for faster and more efficient data processing. SingleStore's lack of foreign keys in DDL is mitigated by the use of filters in insert...select statements and pipelines, which can be used to enforce referential integrity and uniqueness checks with inserts or stored procedures. The platform's scalability and performance make it well-suited for applications that require sub-second latency and high concurrency, such as those involving real-time streaming analytics and AI workloads.
