All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<Statistics.Builder,Statistics>

@Generated(value="software.amazon.awssdk:codegen")
public final class Statistics
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Statistics.Builder,Statistics>

Contains statistics information. The DFE engine uses information about the data in your Neptune graph to make effective trade-offs when planning query execution. This information takes the form of statistics that include so-called characteristic sets and predicate statistics that can guide query planning. See Managing statistics for the Neptune DFE to use.
