In this PR, we will control whether the external data source query is a push-down function parameter in the filter condition, changing the enable_fun_pushdown of fe conf to the enable_ext_func_pred_pushdown of the variable
Fix cte rewrite by mv wrongly when query has scalar aggregate but view no
For example as following, it should not be rewritten by materialized view successfully
// materialzied view define
def mv20_1 = """
select
l_shipmode,
l_shipinstruct,
sum(l_extendedprice),
count()
from lineitem
left join
orders on lineitem.L_ORDERKEY = orders.O_ORDERKEY
group by
l_shipmode,
l_shipinstruct;
"""
// query sql
def query20_1 =
"""
select
sum(l_extendedprice),
count()
from lineitem
left join
orders
on lineitem.L_ORDERKEY = orders.O_ORDERKEY
"""
Fix predicates compensation by mistake
For example as following, it can return right result, but it's wrong earlier.
// materialzied view define
def mv7_1 = """
select l_shipdate, o_orderdate, l_partkey, l_suppkey
from lineitem
left join orders
on lineitem.l_orderkey = orders.o_orderkey
where l_shipdate = '2023-12-08' and o_orderdate = '2023-12-08';
"""
// query sql
def query7_1 = """
select l_shipdate, o_orderdate, l_partkey, l_suppkey
from (select * from lineitem where l_shipdate = '2023-10-17' ) t1
left join orders
on t1.l_orderkey = orders.o_orderkey;

and optimize some code usage and add more comment for method
The `ADMIN SHOW` statement can not be executed with high version of mysql 8.x jdbc driver.
So I rename these statement, remove the `ADMIN` keywords.
1. ADMIN SHOW CONFIG -> SHOW CONFIG
2. ADMIN SHOW REPLICA -> SHOW REPLICA
3. ADMIN DIAGNOSE TABLET -> SHOW TABLET DIAGNOSIS
4. ADMIN SHOW TABLET -> SHOW TABLET
for compatibility, the old statements are still supported, but not recommend to use.
They will be removed in later version
The signatures of functions in these PRs should be more standard:
#27342,
#25510,
#20936,
including the following:
ipv4numtostring,
ipv4stringtonum,
ipv4stringtonumordefault,
ipv4stringtonumornull,
ipv6numtostring.
This PR will add necessary underscores between the words of each of them,
like changing ipv4numtostring to ipv4_num_to_string.
