Kouhei Sutou commented on ARROW-14088:
--------------------------------------
{noformat}
Arrow::Table.load("parquet_dataset", format: :parquet, filter:
["greater_equal", :a, 7])
{noformat}
{{filter}} uses S-expression style for now. We'll improve the API by
ARROW-14360 such as {{filter: ->() \{a >= 7\}}}.
