查阅AliSQL代码的时候，发现thread_handing只有三个选项值，不包含thread_pool，是不支持线程池了么？

[jaredzhu]

static Sys_var_enum Sys_thread_handling(
"thread_handling",
"Define threads usage for handling queries, one of "
"one-thread-per-connection, no-threads, loaded-dynamically"
, READ_ONLY GLOBAL_VAR(thread_handling), CMD_LINE(REQUIRED_ARG),
thread_handling_names, DEFAULT(0));

static Sys_var_enum Sys_thread_handling(
"thread_handling",
"Define threads usage for handling queries, one of "
"one-thread-per-connection, no-threads"
#ifdef HAVE_POOL_OF_THREADS
", pool-of-threads"
#endif
, READ_ONLY GLOBAL_VAR(thread_handling), CMD_LINE(REQUIRED_ARG),
thread_handling_names,
DEFAULT(DEFAULT_THREAD_HANDLING)
);
这个是percona的代码，pool-of-threads 特性在AliSQL是不支持么？或者是用什么方式替代了？

AliSQL是基于Oracle 版本的，Oracle版本默认没有线程池，我们会在后续将内部实现的版本开源出来。
