Constant

Emits a fixed, predefined value into the pipeline on every tick, independent of any input.

Use this when

• You want to inject a tunable threshold, reference value, or default into a pipeline without hardcoding it inside a component.
• You are testing or experimenting with fixed inputs during development.
• A downstream component expects a continuous stream of a known value.

What it does

Streams exactly one pre-defined value repeatedly. The value is supplied as a parameter, so it is visible and configurable from the pipeline instead of buried in component code.

Inputs

This transformation takes no inputs.

Outputs

Type	Description
t	The constant value, emitted forever.

Parameters

Name	Type	Description
value	t	The value to emit. Type matches the output.

Works best with

• A downstream component that expects a static threshold or configuration stream.
• Filter — feed a constant threshold into comparisons.

Caveats

• The value never changes at runtime. To change it, redeploy the pipeline.
• Constants still consume a stream slot — design pipelines accordingly.
