Pipe verbs

In plain English:
Pipe verbs are small functions you chain with the | operator. They now work seamlessly with VirtualCube, so streaming tiles pass through the same verbs you already use on small cubes.

What this page helps you do:
- See how to read and write pipe expressions - Understand verb behavior in streaming mode - Debug tile-aware runs without changing your code

Pipe refresher with streaming

from cubedynamics import pipe, verbs as v

result = (
    pipe(cube)
    | v.anomaly(dim="time")
    | v.month_filter([6, 7, 8])
    | v.mean(dim=("y", "x"))
)

If cube is a VirtualCube, each tile flows through the same chain, and the reductions keep incremental statistics under the hood.

Verb behavior in streaming mode

• Transforms run on each tile independently.
• Reductions (mean, variance, std, anomaly) keep running totals so the final output matches in-memory results.
• IO and visualization verbs request tiles lazily; plotting functions stream data without loading the whole cube first.

Debugging verbs with tiles

• Print the pipe input to confirm whether it is virtual.
• Use v.peek() or similar custom verbs to log shapes per tile.
• If a verb needs full context (rare), call .materialize() first, but only for manageable sizes.
