TupleDomainParquetPredicate

public TupleDomainParquetPredicate(TupleDomain<org.apache.parquet.column.ColumnDescriptor> effectivePredicate,
                                   List<RichColumnDescriptor> columns,
                                   org.joda.time.DateTimeZone timeZone)

Method Detail

matches

public boolean matches(long numberOfRows,
                       Map<org.apache.parquet.column.ColumnDescriptor,org.apache.parquet.column.statistics.Statistics<?>> statistics,
                       ParquetDataSourceId id)
                throws ParquetCorruptionException

Description copied from interface: Predicate

Should the Parquet Reader process a file section with the specified statistics.

Specified by:

matches in interface Predicate

Parameters:

numberOfRows - the number of rows in the segment; this can be used with Statistics to determine if a column is only null

statistics - column statistics

id - Parquet file name

Throws:

ParquetCorruptionException

matches

public boolean matches(DictionaryDescriptor dictionary)

Description copied from interface: Predicate

Should the Parquet Reader process a file section with the specified dictionary based on that single dictionary. This is safe to check repeatedly to avoid loading more parquet dictionaries if the section can already be eliminated.

Specified by:

matches in interface Predicate

Parameters:

dictionary - The single column dictionary

matches

public boolean matches(long numberOfRows,
                       org.apache.parquet.internal.filter2.columnindex.ColumnIndexStore columnIndexStore,
                       ParquetDataSourceId id)
                throws ParquetCorruptionException

Description copied from interface: Predicate

Should the Parquet Reader process a file section with the specified statistics.

Specified by:

matches in interface Predicate

Parameters:

numberOfRows - the number of rows in the segment; this can be used with Statistics to determine if a column is only null

columnIndexStore - column index (statistics) store

id - Parquet file name

Throws:

ParquetCorruptionException

toParquetFilter

public Optional<org.apache.parquet.filter2.predicate.FilterPredicate> toParquetFilter(org.joda.time.DateTimeZone timeZone)

Description copied from interface: Predicate

Convert Predicate to Parquet filter if possible.

Specified by:

toParquetFilter in interface Predicate

Parameters:

timeZone - current Parquet timezone

Returns:

Converted Parquet filter or null if conversion not possible
