require "datafusion"

context = DataFusion::SessionContext.new table = Arrow::Table.new(boolean: [true, nil, false], integer: [1, 2, nil]) context.register("data", table) data_frame = context.sql("SELECT * FROM data WHERE boolean = true") puts(data_frame.to_table)

There is another Ruby bindings available at gem "arrow-datafusion". It focus on running query on Object Store and does not bundle with gem "red-arrow".
