Main changes:
1. If fqdn is enabled in the configuration file, when fe starts, localAddr will obtain fqdn instead of IP, priority_ Networks will fail
2. The IP and host names of Backend and Front are combined into one field, host. When fqdn is enabled, it represents the host name, and when not enabled, it represents the IP address
3. The communication between clusters directly uses fqdn, and various Connection pool add authentication mechanisms to prevent the IP address of the domain name from changing and the connection between nodes from making errors
4. No longer requires polling to verify if the IP has changed, delete fqdnManager
5. Change the method of verifying the legitimacy of nodes between FEs from obtaining client IP to displaying the identity of the transmitting node itself in the HTTP request header or the message body of the throttle
6. When processing the heartbeat, if BE finds that the host stored by itself is inconsistent with the host stored by the master, after verifying the legitimacy of the host, it will change its own host instead of directly reporting an error
7. Simplify the generation logic of fe name
Scope of influence:
1. Establishing communication connections between clusters
2. Determine whether it is the same node through attributes such as IP
3. Print Log
4. Information display
5. Address Splicing
6. k8s deployment
7. Upgrade compatibility
Test plan:
1. Change the IP address of the node, while keeping the fqdn unchanged, change the IP addresses of fe and be, and verify whether the cluster can read and write data normally
2. Use the master code to generate metadata, and use the previous metadata on the current pr to verify whether it is compatible with the old version (upgrading is no longer supported if fqdn has been enabled before)
3. Deploy fe and be clusters using k8s to verify whether the cluster can read and write data normally
4. According to https://doris.apache.org/zh-CN/docs/dev/admin-manual/cluster-management/fqdn?_highlight=fqdn#%E6%97%A7%E9%9B%86%E7%BE%A4%E5%90%AF%E7%94%A8fqdn Upgrading old clusters
5. Use streamload to specify the fqdn of fe and be to import data separately
6. Use different users to start transactions and write data using insert statements
1. fixed some error regressions (results error with big nstance_num due to incorrect order by).
2. if set parallel_fragment_exec_instance_num to 0, the concurrency in the Pipeline execution engine will automatically be set to half of the number of CPU cores.
3. add limit to parallel_fragment_exec_instance_num that it cannot be set to more than fe.conf::max_instance_num(Default: 128)
```
mysql [(none)]>set parallel_fragment_exec_instance_num = 514;
ERROR 1231 (42000): errCode = 2, detailMessage = Variable 'parallel_fragment_exec_instance_num' can't be set to the value of '514(Should not be set to more than 128)'
```
Supplement the documentation of be-clion-dev, avoid the problem of undefined DORIS_JAVA_HOME and inability to find jni.h when using clion development without directly compiling through build.sh
Complete the classification of header files in pch.h and introduce some header files that are not frequently modified in doris.
Separate the declaration and definition in common/config.h. If you need to modify the default configuration now, please modify it in common/config.cpp.
gen_cpp/version.h is regenerated every time it is recompiled, which may cause PCH to fail, so now you need to get the version information indirectly rather than directly.
- Implements ORC lazy materialization, integrate with the implementation of https://github.com/apache/doris-thirdparty/pull/56 and https://github.com/apache/doris-thirdparty/pull/62.
- Refactor code: Move `execute_conjuncts()` and `execute_conjuncts_and_filter_block()` in `parquet_group_reader `to `VExprContext`, used by parquet reader and orc reader.
- Add session variables `enable_parquet_lazy_materialization` and `enable_orc_lazy_materialization` to control whether enable lazy materialization.
- Modify `build.sh` to update apache-orc submodule or download package every time.
when I use mysql-jdbc 5.1.47 create a doris jdbc catalog, the largeint cannot select
When mysql-jdbc reads largeint, it will convert the format to string because it is too long
mysql> select `largeint` from type3;
ERROR 1105 (HY000): errCode = 2, detailMessage = (127.0.0.1)[INTERNAL_ERROR]Fail to convert jdbc type of java.lang.String to doris type LARGEINT on column: largeint. You need to check this column type between external table and doris table.
Support querying data from the Nebula graph database
This feature comes from the needs of commercial customers who have used Doris and Nebula, hoping to connect these two databases
changes mainly include:
* add New Graph Database JDBC Type
* Adapt the type and map the graph to the Doris type
This pr does three things:
1. add `delete_existing_files` property for outfile/export. If `delete_existing_files = true`, export/outfile will delete all files under file_path first.
2. add p2 test for export
3. modify docs
Fix dict cols not be converted back to string type in some cases, which includes introduced by #19039.
For dict cols, we will convert dict cols to int32 type firstly, then convert back to string type after read block.
The block will be reuse it, so it is necessary to convert it back.
This work is in the early stage, current progress is not accurate because the scan range will be too large
for gathering information, what's more, only file scan node and import job support new progress manager
## How it works
for example, when we use the following load query:
```
LOAD LABEL test_broker_load
(
DATA INFILE("XXX")
INTO TABLE `XXX`
......
)
```
Initial Progress: the query will call `BrokerLoadJob` to create job, then `coordinator` is called to calculate scan range and its location.
Update Progress: BE will report runtime_state to FE and FE update progress status according to jobID and fragmentID
we can use `show load` to see the progress
PENDING:
```
State: PENDING
Progress: 0.00%
```
LOADING:
```
State: LOADING
Progress: 14.29% (1/7)
```
FINISH:
```
State: FINISHED
Progress: 100.00% (7/7)
```
At current time, full output of `show load\G` looks like:
```

Comment:
```
## TODO:
1. The current partition granularity of scan range is too large, resulting in an uneven loading process for progress."
2. Only broker load supports the new Progress Manager, support progress for other query
For files less than 5MB, we don't need to use multi part upload which would at least takes 3 network IO.
Instead we can just call PutObject which only takes one shot.
The original method signature is Block VExprContext::get_output_block_after_execute_exprs(
const std::vectorvectorized::VExprContext*& output_vexpr_ctxs, const Block& input_block,
Status& status)
It return error status as a out parameter and the block as return value. It has to check the block.rows == 0 and then check error status.
It is not conforming to the convention.

Add file cache metrics and management.
1. Get file cache metrics
> If the performance of file cache is not efficient, there are currently no metrics to investigate the cause. In practice, hit ratio, disk usage, and segments removed status are very important information.
API: `http://be_host:be_webserver_port/metrics`
File cache metrics for each base path start with `doris_be_file_cache_` prefix. `hits_ratio` is the hit ratio of the cache since BE startup; `removed_elements` is the num of removed segment files since BE startup; Every cache path has three queues: index, normal and disposable. The capacity ratio of the three queues is 1:17:2.
```
doris_be_file_cache_hits_ratio{path="/mnt/datadisk1/gaoxin/file_cache"} 0.500000
doris_be_file_cache_hits_ratio{path="/mnt/datadisk1/gaoxin/small_file_cache"} 0.500000
doris_be_file_cache_removed_elements{path="/mnt/datadisk1/gaoxin/file_cache"} 0
doris_be_file_cache_removed_elements{path="/mnt/datadisk1/gaoxin/small_file_cache"} 0
doris_be_file_cache_normal_queue_max_size{path="/mnt/datadisk1/gaoxin/file_cache"} 912680550400
doris_be_file_cache_normal_queue_max_size{path="/mnt/datadisk1/gaoxin/small_file_cache"} 8500000000
doris_be_file_cache_normal_queue_max_elements{path="/mnt/datadisk1/gaoxin/file_cache"} 217600
doris_be_file_cache_normal_queue_max_elements{path="/mnt/datadisk1/gaoxin/small_file_cache"} 102400
doris_be_file_cache_normal_queue_curr_size{path="/mnt/datadisk1/gaoxin/file_cache"} 14129846
doris_be_file_cache_normal_queue_curr_size{path="/mnt/datadisk1/gaoxin/small_file_cache"} 14874904
doris_be_file_cache_normal_queue_curr_elements{path="/mnt/datadisk1/gaoxin/file_cache"} 18
doris_be_file_cache_normal_queue_curr_elements{path="/mnt/datadisk1/gaoxin/small_file_cache"} 22
...
```
2. Release file cache
> Frequent segment files swapping can seriously affect the performance of file cache. Adding a deletion interface helps users clean up the file cache.
API: `http://be_host:be_webserver_port/api/file_cache?op=release&base_path=${file_cache_base_path}`
Return the number of released segment files. If `base_path` is not provide in url, all cache paths will be released.
It's thread-safe to call this api, so only the segment files not been read currently can be released.
```
{"released_elements":22}
```
3. Specify the base path to store cache data
> Currently, regression testing lacks test cases of file cache, which cannot guarantee the stability of file cache. This interface is generally used in regression testing scenarios. Different queries use different paths to verify different usage cases and performance.
User can set session variable `file_cache_base_path` to specify the base path to store cache data. `file_cache_base_path="random"` as default, means chosing a random path from cached paths to store cache data. If `file_cache_base_path` is not one of the base paths in BE configuration, a random path is used.

Currently, exec node save exprcontext**, but the object is in object pool, the code is very unclear. we could just use exprcontext*.
