How does a Singlestore database with a single leaf function?

edit

A SingleStore database with a single leaf functions as a standalone database. In this configuration, there is only one node in the cluster that operates as both the aggregator and the leaf node. It can handle all query processing and store all data.

While the single leaf configuration may not provide the same scale-out benefits as a multi-node cluster, it can be a cost-effective option for smaller workloads or environments where a cluster is not required.

In this setup, the SingleStore database is installed on a single machine and runs as a service. The machine must meet the hardware and software requirements for the database.

In summary, a SingleStore database with a single leaf can function as a standalone database, handling all query processing and storing all data on a single machine.
