How are SingleStore DB and Apache Spark related?

SingleStore DB and Apache Spark are both distributed, in-memory technologies. SingleStore DB is a SQL database, while Spark is a general computation framework. SingleStore DB has tight integration with Apache Spark through its SingleStore Spark Connector offering. For instance, with SingleStore DB and Spark clusters deployed, users can extract data from real-time sources such as Kafka, run the data through a Spark machine learning library model, and store the model result into SingleStore DB to be persisted and queryable.
