@MemberGetter
public static int kInspectAllFragments()

See fragments property.

fragments

public int fragments()

Indicate how many fragments should be inspected to infer the unified dataset schema. Limiting the number of fragments accessed improves the latency of the discovery process when dealing with a high number of fragments and/or high latency file systems. The default value of 1 inspects the schema of the first (in no particular order) fragment only. If the dataset has a uniform schema for all fragments, this default is the optimal value. In order to inspect all fragments and robustly unify their potentially varying schemas, set this option to kInspectAllFragments. A value of 0 disables inspection of fragments altogether so only the partitioning schema will be inspected.
