Problem:
when we create table with datatype varchar(), we regard it to be max length by default. But when we desc, it does not show
real length but show varchar()
Reason:
when we upgrade version from 2.0.1 to 2.0.2, we support new feature of creating varchar(), and it shows the same way with
ddl schema. So user would confuse of the length of varchar
Solved:
change the showing of varchar() to varchar(65533), which in compatible with hive

* [fix](planner) Fix sample partition table #25912 (#26399)

In the past, two conditions needed to be met when sampling a partitioned table: 1. Data is evenly distributed between partitions; 2. Data is evenly distributed between buckets. Finally, the number of sampled rows in each partition and each bucket is the same.

Now, sampling will be proportional to the number of partitioned and bucketed rows.

* [fix](Nereids) RewriteCteChildren not work with cost based rewritter (#26326) (#26530)

we use a map to record rewrite cte children result to avoid rewrite
twice in cost based rewritter. However, we record cte outer and
inner in one map, and use null as outer result's key, use cte id as
inner result's key. This is wrong, because every anchor has an outer,
and we could only record one outer. So when we use the cache in cost
based rewritter, we get wrong outer plan from the cache. Then the error
will be thrown as below:

Use field datatype such as decimal(10, 0) to create table like. Because the scale is 0, the precision and scale will lost when create table like done. this will fix the bug.

**Before fix, create table with following SQL**:
CREATE TABLE IF NOT EXISTS db_test.table_test
(
    `name` varchar COMMENT "1m size",
    `id` SMALLINT COMMENT "[-32768, 32767]",
    `timestamp0` decimal null comment "c0",
    `timestamp1` decimal(38, 0) null comment "c1"
)
DISTRIBUTED BY HASH(`id`) BUCKETS 1
PROPERTIES ('replication_num' = '1');

**and Then run**
CREATE TABLE db_test.table_test_like LIKE db_test.table_test
SHOW CREATE TABLE db_test.table_test_like;

the field `timestamp1` will be decimal(9, 0), it's wrong. this will fix it.

* [Opt](orc-reader) Optimize orc string dict filter in not_single_conjunct case. (#26386) (#26696)

Optimize orc/parquet string dict filter in not_single_conjunct case. We can optimize this processing to filter block firstly by dict code, then filter by not_single_conjunct. Because dict code is int, it will filter faster than string.

For example:
```
select count(l_receiptdate) from lineitem_date_as_string where l_shipmode in ('MAIL', 'SHIP') and l_commitdate < l_receiptdate  and l_receiptdate >= '1994-01-01' and l_receiptdate < '1995-01-01';
```
 `l_receiptdate` and `l_shipmode` will using string dict filtering, and `l_commitdate < l_receiptdate` is the an not_single_conjunct which contains dict filter field. We can optimize this processing to filter block firstly by dict code, then filter by not_single_conjunct. Because dict code is int, it will filter faster than string.

Before:
 mysql> select count(l_receiptdate) from lineitem_date_as_string where l_shipmode in ('MAIL', 'SHIP') and l_commitdate < l_receiptdate  and l_receiptdate >= '1994-01-01' and l_receiptdate < '1995-01-01';
+----------------------+
| count(l_receiptdate) |
+----------------------+
|             49314694 |
+----------------------+
1 row in set (6.87 sec)

After:
mysql> select count(l_receiptdate) from lineitem_date_as_string where l_shipmode in ('MAIL', 'SHIP') and l_commitdate < l_receiptdate  and l_receiptdate >= '1994-01-01' and l_receiptdate < '1995-01-01';
+----------------------+

Improve the accuracy of sample stats collection. For non distribution columns, use

where `f1` is the number of distinct values that occurred exactly once in our sample of n rows (from a total of N),
and `d` is the total number of distinct values in the sample.

For distribution columns, use `ndv(n) * fraction of tablets sampled` for NDV.

For very large tablet to sample, use limit to control the total lines to scan (for non key column only, because key column is sorted and will be inaccurate using limit).

Fixed the bug of incomplete query results when querying information_schema.rowsets in the case of multiple BEs.

The reason is that the schema scanner sends the scan fragment to one of multiple bes, and be queries the information of fe through rpc. Since the rowsets information requires information about all BEs, the scan fragment needs to be sent to all BEs.

* [cherry-pick](fe) select BE local broker to scan Hive table when 'broker.name' in hms catalog is specified (#27122) (#27252)

Since #24830 introduce `broker.name` in hms catalog, data scan will run on specified brokers.
And [doris operator](https://github.com/selectdb/doris-operator) support BE and broker deployed in same pod, BE access local broker is the fastest approach to access data.
In previous logic, every inputSplit will select one BE to execute,  then randomly select one broker for actual data access, BE and related broker are always located on  separate K8S pod.
This pr optimizes the broker select strategy to prioritize BE-local broker when `broker.name` is specified in hms catalog.

…ache#26850)

Problem:
when we create table with datatype varchar(), we regard it to be max length by default. But when we desc, it does not show
real length but show varchar()
Reason:
when we upgrade version from 2.0.1 to 2.0.2, we support new feature of creating varchar(), and it shows the same way with
ddl schema. So user would confuse of the length of varchar
Solved:
change the showing of varchar() to varchar(65533), which in compatible with hive
