pub struct Blanas;

Expand description

Generator for the Blanas data set.

The Blanas data set is taken from the paper Blanas et al. “Design and evaluation of main memory hash join algorithms for multi-core CPUs” in SIGMOD 2011.

The paper uses 8-byte keys / 16-byte tuples.

Implementations

source

impl Blanas

source

pub fn primary_key_len() -> usize

Rows in the primary key relation.

source

pub fn foreign_key_len() -> usize

Rows in the foreign key relation.

source

pub fn gen<T: Copy + Send + KeyAttribute + FromPrimitive>(
 pk_attr: &mut [T],
 fk_attr: &mut [T],
 selectivity: Option<u32>
) -> Result<()>

Generate the Blanas data set.

Requires a slice for the primary key attribute, and a slice for the foreign key attribute. Both slices must have the lengths specified by the primary_key_len() and foreign_key_len() functions.

selectivity specifies the join selectivity in percent. An according percentage of keys are set to the NULL value. By default (None), the selectivity is 100%.
