Sample Paths

Randomly sample paths (and all their events).

Exactly one of n or frac must be provided (mirrors pandas.DataFrame.sample).

Usage

stream.sample_paths(n=1000)
stream.sample_paths(frac=0.1, random_state=42)  # 10 % of paths

Parameter	Type	Description
`n`	`int, optional`	Number of paths to keep.
`frac`	`float, optional`	Fraction of total paths to keep, in the range `(0.0, 1.0]`. Passing `1.0` returns the eventstream unchanged.
`random_state`	`int, optional`	Seed for the random number generator; pass an integer for reproducible results.
`path_col`	`str, optional`	Path ID column override; defaults to `schema.path_col`.
