Using asynchronous loggers, file descriptors are still held by multiple threads #3498
Description
The following content was first set in the code
spdlog::flush_every(std::chrono::milliseconds(logInfo.flush_every)); spdlog::init_thread_pool(logInfo.pool_size, logInfo.thread_num);
And then created an asynchronous recorder
logger = spdlog::create_async<spdlog::sinks::rotating_file_sink_st>(moduleInfo.logger_name, moduleInfo.log_file_path, moduleInfo.max_size, moduleInfo.max_files);
But the process descriptor is still held by multiple threads, does this mean that we are still using synchronous recorder mode？
