description: Largest non-null value of the field.
kind: operator

examples_tags: [financial, streaming-friendly]

Use when

Largest value of a numeric or date field, over all rows or per group.

Questions it answers:

• What is the latest order date in each region?
• Is any order value implausibly large?

Use something else:

• AGG_MIN when you want the smallest value.
• AGG_PERCENTILE when one extreme row would mislead and you want a high value that ignores it.
• AGG_RANGE when you want the distance between smallest and largest.

Params

None.

Inputs

Output

Scalar float64. Per-group when wired under a grouper.

Components

Universal floor {n, n_null} plus operator-specific:

• Mergeability: Mergeable
• Streaming: per-chunk emits running max

Gotchas

• Null rows skipped; n_null counts them.
• All-null cohort → emits NaN.
