6726c9bf2f [improvement](compaction) reduce tablet skip compaction time (#44273) (#44791) 
pick master #44273

The time for tablet skip compaction is 120 seconds, which is too long.
In the scenario of high-frequency import (mow), it leads to a high
compaction score. Therefore, reducing the skip time to 10 seconds is
necessary.

d1d52ae68c [feature](compaction) Add an http action for visibility of compaction score on each tablet (#38489) (#40826) 
pick: #38489 

Usage:
1. `curl http://be_ip:be_host/api/compaction_score?top_n=10` Returns a
json object contains compaction score for top n, n=top_n.
```
[
    {
        "compaction_score": "5",
        "tablet_id": "42595"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42587"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42593"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42597"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42589"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42599"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42601"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42591"
    },
    {
        "compaction_score": "5",
        "tablet_id": "42585"
    },
    {
        "compaction_score": "4",
        "tablet_id": "10034"
    }
]
```
If top_n is not specified, return all compaction score for all tablets.
If top_n is illegal, raise an error.
```
invalid argument: top_n=wrong
```

2. `curl http://be_ip:be_host/api/compaction_score?sync_meta=true`
`sync_meta` is only available on cloud mode, will sync meta from meta
service. It can cooperate with top_n.
If add param `sync_meta` on non-cloud mode, will raise an error.
```
sync meta is only available for cloud mode
```

3. In the future, this endpoint may extend other utility, like fetching
tablet compaction score by table id, etc.

341b2e0693 [enhancement](compaction) Abort compaction tasks when correspoding tablet states have been changed (#40271) (#40828) 
## Proposed changes

pick: #40271

1. Change the standard for cumu compaction capability. Tablets under
state `running` or `not ready` are capable to do cumulative compaction.
2. Abort a compaction task at the beginning when the tablet is no more
capable to do compaction.

If full compaction is running, the output will be

"msg" : "compaction task for this tablet is running",
"tablet_id" : 10084,

"run_status" : false,
"msg" : "compaction task for this tablet is not running",
"tablet_id" : 10084,
"compact_type" : "full"
}

* [Fix](partial update) Fix rowset not found error when doing partial update (#34112)

Cause: In the logic of partial column updates, the existing data columns are read first, and then the data is supplemented and written back. During the reading process, initialization involves initially fetching rowset IDs, and the actual rowset object is fetched only when needed later. However, between fetching the rowset IDs and the rowset object, compaction may occur, turning the old rowset into a stale rowset. If too much time passes, the stale rowset might be directly deleted. Thus, when the rowset object is needed for an update, it cannot be found. Although the update operation with partial column logic should be able to read all keys and should not encounter new keys, if the rowset disappears, the Backend (BE) will consider these keys as missing. Consequently, it will check whether other columns have default values or are nullable. If this check fails, the aforementioned error is thrown.

Solution: To avoid such issues during partial column updates, the initialization step should involve fetching both the rowset IDs and the shared pointer to the rowset object simultaneously. This ensures that the rowset can always be found during data retrieval.
