Detailed Description
Class to build parquet_writer_options.
Definition at line 1274 of file parquet.hpp.
Constructor & Destructor Documentation
◆ parquet_writer_options_builder() [1/2]
|
explicitdefault |
Default constructor.
This has been added since Cython requires a default constructor to create objects on stack.
◆ parquet_writer_options_builder() [2/2]
|
explicit |
Constructor from sink and table.
- Parameters
-
sink The sink used for writer output table Table to be written to output
Member Function Documentation
◆ column_chunks_file_paths()
| parquet_writer_options_builder& cudf::io::parquet_writer_options_builder::column_chunks_file_paths | ( | std::vector< std::string > | file_paths | ) |
Sets column chunks file path to be set in the raw output metadata.
- Parameters
-
file_paths Vector of Strings which indicates file path. Must be same size as number of data sinks
- Returns
- this for chaining
◆ partitions()
| parquet_writer_options_builder& cudf::io::parquet_writer_options_builder::partitions | ( | std::vector< partition_info > | partitions | ) |
Sets partitions in parquet_writer_options.
- Parameters
-
partitions Partitions of input table in {start_row, num_rows} pairs. If specified, must be same size as number of sinks in sink_info
- Returns
- this for chaining
