Constructor Detail

HoodieMetadataColumnStats

public HoodieMetadataColumnStats()

Default constructor. Note that this does not initialize fields to their default values from the schema. If that is desired then one should use newBuilder().

HoodieMetadataColumnStats

public HoodieMetadataColumnStats(String fileName,
                                 String columnName,
                                 Object minValue,
                                 Object maxValue,
                                 Long valueCount,
                                 Long nullCount,
                                 Long totalSize,
                                 Long totalUncompressedSize,
                                 Boolean isDeleted)

All-args constructor.

Parameters:

fileName - File name for which this column statistics applies

columnName - Column name for which this column statistics applies

minValue - Minimum value in the range. Based on user data table schema, we can convert this to appropriate type

maxValue - Maximum value in the range. Based on user data table schema, we can convert it to appropriate type

valueCount - Total count of values

nullCount - Total count of null values

totalSize - Total storage size on disk

totalUncompressedSize - Total uncompressed storage size on disk

isDeleted - Column range entry valid/deleted flag
