Open the ForCS log_Summary Arrow dataset for one or more scenarios

Opens each existing <scenario>/_aggregates/forcs_log_summary root as an Arrow dataset partitioned by replicate. A single root opens directly; multiple roots under different parents are opened individually and combined into a UnionDataset (Arrow cannot treat Hive trees under different parents as one dataset). Missing roots (e.g. scenarios whose runs errored) are dropped.

Usage

open_forcs_log_summary_dataset(dataset_roots)

Arguments

dataset_roots

Character vector of <scenario>/_aggregates/forcs_log_summary paths.

Value

An Arrow Dataset (lazy), or NULL if no roots exist.
