Read Primitives — Expression Order By

Read Primitives benchmark · all Read Primitives queries

Sort on computed expressions with DESC ordering

Representative SQL

Rendered for DataFusion with default parameters.

SELECT
  l_orderkey,
  l_partkey,
  l_quantity * l_extendedprice AS total_value
FROM lineitem
ORDER BY
  l_quantity * l_extendedprice DESC
LIMIT 100

Representative DataFrame

Expression family (Polars, PySpark, DataFusion), default parameters.

def orderby_expression_expression_impl(ctx: DataFrameContext) -> Any:
    return (
        ctx.get_table("lineitem")
        .with_columns((ctx.col("l_quantity") * ctx.col("l_extendedprice")).alias("total_value"))
        .sort("total_value", descending=True)
        .select("l_orderkey", "l_partkey", "total_value")
        .limit(100)
    )

Get the exact query for your run

The blocks above are representative. To get the precise statement a specific platform runs at a specific scale, substitute your own values:

from benchbox import ReadPrimitives

bench = ReadPrimitives(scale_factor=0.01)            # your scale factor
queries = bench.get_queries(dialect="datafusion")   # your platform's dialect; drop dialect= for native SQL
print(queries['orderby_bigint_expression'])

For the DataFrame form:

from benchbox.core.query_catalog import get_dataframe_render

print(get_dataframe_render('read_primitives', 'orderby_bigint_expression', family="expression").source)  # or family="pandas"
