org.apache.pinot.common.restlet.resources.TableMetadataInfo

public class TableMetadataInfo
extends Object

Class to represent aggregated segment metadata for a table. - When return by server API, columnLengthMap/columnCardinalityMap is the total columnLength/columnCardinality across all segments on that server. - When return by controller API, columnLengthMap/columnCardinalityMap is the average columnLength/columnCardinality across all segments for the given table. - For diskSizeInBytes/numSegments/numRows, both server API and controller API will return the total value across all segments (if a segment has multiple replicas, only consider one replica).
