public static final class SplitStats.Builder
extends Object

Builder for constructing SplitStats instances. Columns are added via addColumn(String) which returns an ordinal for subsequent stat calls. Path segments are deduplicated automatically.

Method Summary

Modifier and Type	Method	Description
int	addColumn(String name)	Adds a column and returns its ordinal.
int	addColumn(String name, long nullCount, Object min, Object max, long sizeBytes)	Adds a column with all stats in a single call and returns its ordinal.
SplitStats	build()
SplitStats.Builder	max(int columnOrdinal, Object max)
SplitStats.Builder	maxUnservable(int columnOrdinal)	Marks the column's MAX as poisoned (unservable): a fold found it incompatible, so it must not be served.
SplitStats.Builder	min(int columnOrdinal, Object min)
SplitStats.Builder	minUnservable(int columnOrdinal)	Marks the column's MIN as poisoned (unservable): a fold found it incompatible, so it must not be served.
SplitStats.Builder	nullCount(int columnOrdinal, long nullCount)
SplitStats.Builder	rowCount(long rowCount)

Method Details

rowCount

public SplitStats.Builder rowCount(long rowCount)

sizeInBytes

public SplitStats.Builder sizeInBytes(long sizeInBytes)

addColumn

public int addColumn(String name)

Adds a column and returns its ordinal. The column name is split on '.' and each segment is deduplicated in the path-segment dictionary.

Throws:

IllegalArgumentException - if a column with the same name was already added

addColumn

public int addColumn(String name,
 long nullCount,
 @Nullable
 Object min,
 @Nullable
 Object max,
 long sizeBytes)

Adds a column with all stats in a single call and returns its ordinal. Use -1 for unknown longs and null for unknown objects.

Throws:

IllegalArgumentException - if a column with the same name was already added

nullCount

public SplitStats.Builder nullCount(int columnOrdinal,
 long nullCount)

valueCount

public SplitStats.Builder valueCount(int columnOrdinal,
 long valueCount)

min

public SplitStats.Builder min(int columnOrdinal,
 Object min)

max

public SplitStats.Builder max(int columnOrdinal,
 Object max)

sizeBytes

public SplitStats.Builder sizeBytes(int columnOrdinal,
 long sizeBytes)

minUnservable

public SplitStats.Builder minUnservable(int columnOrdinal)

Marks the column's MIN as poisoned (unservable): a fold found it incompatible, so it must not be served.

maxUnservable

public SplitStats.Builder maxUnservable(int columnOrdinal)

Marks the column's MAX as poisoned (unservable): a fold found it incompatible, so it must not be served.

build
