# generate payload: full table scan with aggregation
# the SQL is select sum(a+b+e), sum(a*b), sum(a*e), sum(b*e), sum(a*b*e) from test.t_full_table_scan;
# the total table rows is 1000

# generate payload: full table scan without aggregation
# the SQL is select * from test.t_full_table_scan;
# the total table rows is 100

# generate payload: full index lookup with aggregation
# the SQL is select sum(a+e), max(c) from test.t_full_index_lookup use index (idx0);
