Sandbox

A sandbox is an interactive environment you can use to interact with queries before persisting them into a streaming query.

Start a sandbox environment using the START SANDBOX command. This command starts a new temporary cluster in your organization. Once started, the sandbox bootstraps the appropriate resources until it reaches the RUNNING state. At this state, you can run ad hoc queries such as SELECT against DeltaStream relations without persisting them.

Store-level commands such as PRINT ENTITY do not require a sandbox because they read directly from the backing entity in the current store.

Sandboxes stop automatically after 10 minutes if not used. You can also stop them using the STOP SANDBOX command.
