### Description In our online sqls, there are many nested functions calls, such as - `select a.b.c from test_tbl` => `select get_struct_field((get_struct_field(a, b),c) from test_tbl` - `select count(1) from test_tbl where a = 1 and b = 2 and c = 3` => `select count(1) from test_tbl where and(and(a = 1, b = 2), c = 3 )` - `select count(1) from test_tbl where a = 1 or b = 2 or c = 3` => `select count(1) from test_tbl where or(or(a = 1, b = 2), c = 3 )` ..... and these functions can be optimized by make the nested arguments collapsed , which means `get_struct_field((get_struct_field(a, b),c)` => get_struct_field(a, b, c) `and(and(a = 1, b = 2), c = 3 )` => and(a =1, b=2, c=3) `or(or(a=1, b= 2), c=3)` => or(a=1, b=2, c=3) which can reduce the function calls and improve performance. -- This is an automated message from the Apache Git Service.
