SingleStore is a distributed relational database that can be used as an alternative to Oracle in certain scenarios, offering advantages such as faster data processing and analytics capabilities. It has two primary data stores: an in-memory rowstore and a disk-based columnstore, which allows for real-time analytics and stream processing. SingleStore complements Oracle databases by serving as the real-time analytics engine, ingest layer, or stream processing layer, eliminating the need for batch processing and enhancing enterprises' ability to make decisions in real time. With its unique architecture and benefits of scale out, distributed processing, and memory-first technology, SingleStore is an emerging database vendor that can be considered by enterprises with existing Oracle databases.
