benchmarks/sql_benchmarks/predicate_eval/predicate_eval.benchmark.template

# Shared template for every predicate_eval benchmark. Each qNN.benchmark sets
# its `subgroup` directive and then includes this template with parameters:
#   SUBGROUP  subgroup name, also the query sub-directory          (e.g. costsel)
#   QPAD      zero-padded query id, also the query file stem       (e.g. 01)
#   DATASET   load script stem under load/                         (e.g. markers)
#   NAME      criterion display name                               (e.g. costsel_q01_regexp_selective_last)
# Optional (consumed by the load scripts via ${...:-default}):
#   PRED_ROWS      synthetic row count                                  (default 1_000_000)
#   PRED_FILL      filler chars per marker = string-column width knob    (default 30)
#
# The run SQL lives in queries/${SUBGROUP}/q${QPAD}.sql so the WHERE clause is
# readable on its own. The table is always named `t`, so the assert and cleanup
# are uniform across datasets.
#
# The suite is implementation-agnostic and sets no engine config of its own: it
# measures DataFusion's built-in left-deep `AND` short-circuit by default. To
# evaluate a predicate-ordering system under test, set its native config via the
# environment (the bench harness builds its SessionContext with
# SessionConfig::from_env), e.g.
#   DATAFUSION_EXECUTION_ADAPTIVE_FILTER_REORDERING=true
