修复了 pfs_thread_setname 函数影响线程池性能的问题。 修复partition_id 溢出导致 truncate partition crash 的问题。 修复并行查询中相关子查询引用 worker 表字段导致查询结果错误的问题。 修复并行 DDL 中获取了错误 offset 的问题。 修复并行 DDL 在有重复数据的列上添加 unique key 时 crash 的问题。
在Linux系统中,可以使用pthread_setname_np函数来设置线程名称。这个函数不是标准的POSIX线程库的一部分,但在许多Linux发行版中可用。 代码语言:txt 复制 #include <pthread.h> #include <stdio.h> void* thread_function(void* arg) { // 线程执行的代码 return NULL; } int main() { pthread_t thread; ...
