getOrcaStreamEngineMeta

getOrcaStreamEngineMeta(name)

name is a string representing the name of the stream graph. You can provide either the fully qualified name (FQN), such as "catalog_name.orca_graph.graph_name", or just the graph name, like "factors". If only the name is given, the system will automatically complete it using the current catalog.

Retrieve the metadata of all streaming engines in the specified streaming graph.

Return value: a table containing the following fields:

• taskId: ID of the task that owns the engine.
• name: Name of the engine.
• type: Type of the engine.
• schema: Field types of the engine's output table.
• fqn: Fully qualified name defined by setEngineName.
