Add fluent API builder to `data_profile`

1

## Description Added a builder to enable complex initialization of `data_profile` objects. The builder slightly expands the API to make some common uses easier: - Setting distribution no longer requires...

Add `create_random_column` function to the data generator

3

## Description Depends on #11479 Adds an API to create a single random column, so users don't need to create a table even when a single column is required. The...

[BUG] cuIO benchmarks generate larger files than expected

1

cuIO ORC and Parquet benchmarks generate larger files than previously (e.g. GDS blog data). Some observations: - Only the cases where both cardinality and run length are set lead to...

Data profile is often set using multiple setters in a row. Having a fluent API makes such code less verbose. Similar approach is already used to create xyz_reader/writer_options.

[FEA] Implement skipinitialspace read_csv parameter

2

This parameter is already a part of the API, but it is not used internally. From experiments with Pandas, it looks like this parameter is only relevant when determining if...

Separate cuIO IO benchmarks from column type benchmarks

2

Currently cuIO benchmarks cover a cartesian product of IO options and column types, which leads to a large number of cases and long execution time. We can separate the IO...

[FEA] Expand ORC and Parquet benchmarks to cover different stripe/rowgroup sizes

5

Add a set of benchmarks with varying stripe/rowgroup sizes to each affected component: - [ ] ORC reader - [ ] ORC writer - [ ] Parquet reader - [...

[FEA] Use KvikIO by default

2

Future GDS optimizations will be implemented in KvikIO, we should use it by default as soon as it matches the internal implementation in perf Tasks: - [ ] Compare the...

libcudf does not have functions to read metadata of a file without reading (a portion) of the data as well. Exposing an efficient way to get information like column names...
