Method Detail

withColumns

protected ColumnWriterOptions withColumns(String name,
                                          boolean isNullable)

withDecimal

protected ColumnWriterOptions withDecimal(String name,
                                          int precision,
                                          boolean isNullable)

withTimestamp

protected ColumnWriterOptions withTimestamp(String name,
                                            boolean isInt96,
                                            boolean isNullable)

withListColumn

public T withListColumn(ColumnWriterOptions.ListColumnWriterOptions child)

Set the list column meta. Lists should have only one child in ColumnVector, but the metadata expects a LIST column to have two children and the first child to be the ColumnWriterOptions.DUMMY_CHILD. This is the current behavior in cudf and will change in future

Returns:

this for chaining.

withMapColumn

public T withMapColumn(ColumnWriterOptions child)

Set the map column meta.

Returns:

this for chaining.

Returns:

this for chaining.

withNonNullableColumns
