Detailed Description

Builds settings to use for write_orc().

Definition at line 839 of file orc.hpp.

Constructor & Destructor Documentation

orc_writer_options_builder() [1/2]

cudf::io::orc_writer_options_builder::orc_writer_options_builder ( )

default

Default constructor.

This has been added since Cython requires a default constructor to create objects on stack.

orc_writer_options_builder() [2/2]

cudf::io::orc_writer_options_builder::orc_writer_options_builder ( sink_info const &  sink, table_view const &  table  )

inline

Constructor from sink and table.

Parameters

sink	The sink used for writer output
table	Table to be written to output

Definition at line 856 of file orc.hpp.

Member Function Documentation

build()

orc_writer_options&& cudf::io::orc_writer_options_builder::build ( )

inline

move orc_writer_options member once it's built.

This has been added since Cython does not support overloading of conversion operators.

Returns

Built orc_writer_options object's r-value reference

Definition at line 998 of file orc.hpp.

compression()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::compression ( compression_type  comp )

inline

Sets compression type.

Parameters

comp	The compression type to use

Returns

this for chaining

Definition at line 866 of file orc.hpp.

compression_statistics()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::compression_statistics ( std::shared_ptr< writer_compression_statistics > const &  comp_stats )

inline

Sets the pointer to the output compression statistics.

Parameters

comp_stats

Pointer to compression statistics to be filled once writer is done

Returns

this for chaining

Definition at line 967 of file orc.hpp.

enable_dictionary_sort()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::enable_dictionary_sort ( bool  val )

inline

Sets whether string dictionaries should be sorted.

Parameters

val	Boolean value to enable/disable

Returns

this for chaining

Definition at line 980 of file orc.hpp.

enable_statistics()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::enable_statistics ( statistics_freq  val )

inline

Choose granularity of column statistics to be written.

The granularity can be set to:

• cudf::io::STATISTICS_NONE: No statistics are collected.
• cudf::io::ORC_STATISTICS_STRIPE: Statistics are collected for each ORC stripe.
• cudf::io::ORC_STATISTICS_ROWGROUP: Statistics are collected for each ORC row group.

Parameters

val	Level of statistics collection

Returns

this for chaining

Definition at line 883 of file orc.hpp.

key_value_metadata()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::key_value_metadata ( std::map< std::string, std::string >  metadata )

inline

Sets Key-Value footer metadata.

Parameters

metadata

Key-Value footer metadata

Returns

this for chaining

Definition at line 955 of file orc.hpp.

metadata()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::metadata ( table_input_metadata  meta )

inline

Sets associated metadata.

Parameters

meta	Associated metadata

Returns

this for chaining

Definition at line 943 of file orc.hpp.

row_index_stride()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::row_index_stride ( size_type  val )

inline

Sets the row index stride.

Parameters

val	new row index stride

Returns

this for chaining

Definition at line 919 of file orc.hpp.

stripe_size_bytes()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::stripe_size_bytes ( size_t  val )

inline

Sets the maximum stripe size, in bytes.

Parameters

val	maximum stripe size

Returns

this for chaining

Definition at line 895 of file orc.hpp.

stripe_size_rows()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::stripe_size_rows ( size_type  val )

inline

Sets the maximum number of rows in output stripes.

Parameters

val	maximum number or rows

Returns

this for chaining

Definition at line 907 of file orc.hpp.

table()

orc_writer_options_builder& cudf::io::orc_writer_options_builder::table ( table_view  tbl )

inline

Sets table to be written to output.

Parameters

tbl	Table for the output

Returns

this for chaining

Definition at line 931 of file orc.hpp.
