* Revert "[fix](profile) Fix reporting the profile while building the pipeline profile. (#34215)"
This reverts commit eb0d963389e1b7d150cbc18c927091648e0a60f7.
* Revert "[feature](profile) sort pipelineX task by total time #34053"
This reverts commit 67b394f2b0dddab3801d2faa82a91c52ef875e76.
1. Remove an exec node method corresponding to a span and replace it with an exec node corresponding to a span;
2. Fix some problems with tracing in pipeline.
TabletSink and LoadChannel in BE are M: N relationship,
Every once in a while LoadChannel will randomly return its own runtime profile to a TabletSink, so usually all LoadChannel runtime profiles are saved on each TabletSink, and the timeliness of the same LoadChannel profile saved on different TabletSinks is different, and each TabletSink will periodically send fe reports all the LoadChannel profiles saved by itself, and ensures to update the latest LoadChannel profile according to the timestamp.
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.
# Proposed changes
This PR fixed lots of issues when building from source on macOS with Apple M1 chip.
## ATTENTION
The job for supporting macOS with Apple M1 chip is too big and there are lots of unresolved issues during runtime:
1. Some errors with memory tracker occur when BE (RELEASE) starts.
2. Some UT cases fail.
...
Temporarily, the following changes are made on macOS to start BE successfully.
1. Disable memory tracker.
2. Use tcmalloc instead of jemalloc.
This PR kicks off the job. Guys who are interested in this job can continue to fix these runtime issues.
## Use case
```shell
./build.sh -j 8 --be --clean
cd output/be/bin
ulimit -n 60000
./start_be.sh --daemon
```
## Something else
It takes around _**10+**_ minutes to build BE (with prebuilt third-parties) on macOS with M1 chip. We will improve the development experience on macOS greatly when we finish the adaptation job.
1. replace all boost::shared_ptr to std::shared_ptr
2. replace all boost::scopted_ptr to std::unique_ptr
3. replace all boost::scoped_array to std::unique<T[]>
4. replace all boost:thread to std::thread
* [BUG][Profile] Fixed the problem that BE's profile could not add child profile in the specified correct location
bug:
runtime_profile()->add_child(build_phase_profile, false, nullptr);
child profile will add to second location
* Update runtime_profile.cpp
1. Reduce lock conflicts in RuntimeProfile of be;
2. can view query profile when the query is executing;
3. reduce wait time for 'show proc /current_queries'.
We make all MemTrackers shared, in order to show MemTracker real-time consumptions on the web.
As follows:
1. nearly all MemTracker raw ptr -> shared_ptr
2. Use CreateTracker() to create new MemTracker(in order to add itself to its parent)
3. RowBatch & MemPool still use raw ptrs of MemTracker, it's easy to ensure RowBatch & MemPool destructor exec
before MemTracker's destructor. So we don't change these code.
4. MemTracker can use RuntimeProfile's counter to calc consumption. So RuntimeProfile's counter need to be shared
too. We add a shared counter pool to store the shared counter, don't change other counters of RuntimeProfile.
Note that, this PR doesn't change the MemTracker tree structure. So there still have some orphan trackers, e.g. RowBlockV2's MemTracker. If you find some shared MemTrackers are little memory consumption & too time-consuming, you could make them be the orphan, then it's fine to use the raw ptr.
Mainly change:
1. Fix the bug in `update_status(status)` of `PlanFragmentExecutor`.
2. When the FE Coordinator executes `execRemoteFragmentAsync()`, if it finds an RPC error, return a Future with an error code instead of exception.
3. Protect the `_status` in RuntimeState with lock
4. Move the `_runtime_profile` of RuntimeState before the `_obj_pool`, so that the profile will be
deconstructed after the object pool.
5. Remove the unused `ObjectPool` param in RuntimeProfile constructor. If I don't remove it,
RuntimeProfile will depends on the `_obj_pool` in RuntimeProfile.
Add a JSON format for existing metrics like this.
```
{
"tags":
{
"metric":"thread_pool",
"name":"thrift-server-pool",
"type":"active_thread_num"
},
"unit":"number",
"value":3
}
```
I add a new JsonMetricVisitor to handle the transformation.
It's not to modify existing PrometheusMetricVisitor and SimpleCoreMetricVisitor.
Also I add
1. A unit item to indicate the metric better
2. Cloning tablet statistics divided by database.
3. Use white space to replace newline in audit.log
This CL mainly made the following modifications:
1. Delete Invalid method in Running Profile Class.
2. Move Memlimit Counter from blockmgr to fragment and add PeakMemUsage Counter
3. Fix the bug of buffer pool memlimit counter
4. Call compute_time_in_profile() before pretty_print() to show the _local_time_percent without child running profile
5. Add TransferThread ThreadToken count in AveThreadToken Counter
In the past, when we want to modify some BE configs, we have to modify be.conf and then restart BE.
This patch provides a way to modify configs in the type of 'threshold', 'interval', 'enable flag'
when BE is running without restarting it.
You can update a single config once by BE's http API: `be_host:be_http_port/api/update_config?config_name=new_value`
