Enum ParquetReaderUtility.DateCorruptionStatus

java.lang.Object

java.lang.Enum<ParquetReaderUtility.DateCorruptionStatus>

org.apache.drill.exec.store.parquet.ParquetReaderUtility.DateCorruptionStatus

All Implemented Interfaces:

Serializable, Comparable<ParquetReaderUtility.DateCorruptionStatus>

Enclosing class:

ParquetReaderUtility

public static enum ParquetReaderUtility.DateCorruptionStatus
extends Enum<ParquetReaderUtility.DateCorruptionStatus>

For most recently created parquet files, we can determine if we have corrupted dates (see DRILL-4203) based on the file metadata. For older files that lack statistics we must actually test the values in the data pages themselves to see if they are likely corrupt.
