Constructor & Destructor Documentation

chunked_orc_writer_options_builder() [1/2]

cudf::io::chunked_orc_writer_options_builder::chunked_orc_writer_options_builder ( )

default

Default constructor.

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

chunked_orc_writer_options_builder() [2/2]

cudf::io::chunked_orc_writer_options_builder::chunked_orc_writer_options_builder ( sink_info const &  sink )

inlineexplicit

Constructor from sink and table.

Parameters

sink	The sink used for writer output

Definition at line 1130 of file orc.hpp.

Member Function Documentation

build()

chunked_orc_writer_options&& cudf::io::chunked_orc_writer_options_builder::build ( )

inline

move chunked_orc_writer_options member once it's built.

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

Returns

Built chunked_orc_writer_options object's r-value reference

Definition at line 1259 of file orc.hpp.

compression()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1138 of file orc.hpp.

compression_statistics()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1228 of file orc.hpp.

enable_dictionary_sort()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1241 of file orc.hpp.

enable_statistics()

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

inline

Choose granularity of statistics collection.

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	Frequency of statistics collection

Returns

this for chaining

Definition at line 1155 of file orc.hpp.

key_value_metadata()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1215 of file orc.hpp.

metadata()

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

inline

Sets associated metadata.

Parameters

meta	Associated metadata

Returns

this for chaining

Definition at line 1203 of file orc.hpp.

row_index_stride()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1191 of file orc.hpp.

stripe_size_bytes()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1167 of file orc.hpp.

stripe_size_rows()

chunked_orc_writer_options_builder& cudf::io::chunked_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 1179 of file orc.hpp.
