In the debate over NoSQL vs. SQL databases, SingleStore takes a neutral stance, acknowledging benefits to both approaches. NoSQL databases like MongoDB offer flexibility and schema-free data storage, while SQL databases provide structured data with predefined schemas, ensuring data quality and querying speed. However, as companies grow, their initial infrastructure may not scale well, leading to challenges such as incompatible aggregation queries and the need for custom solutions. SingleStore Kai aims to address these issues by providing a distributed database with automatic shard management and scale-out architecture, supporting all types of joins, while allowing users to keep existing business logic in MongoDB query language or augment/replace it with SQL.
