reason for not-support used in init_by_lua with lua-resty-mysql

Hi,

Tittle is all.

I want to know that reason.

Sorry for my stupid question.

Because, lua-resty-memcached is support that.

Are there some big probrem?

I want to use lua-resty-mysql in 'init_by_lua'.

In my case, using shared DICT and if nginx restart then shared DICT is gone.

So I need some auto-recovery technic, and lua-resty-mysql in 'init_by_lua' is the best way I thougt.

For example, if nginx restart then, pull DICT data from database with lua-resty-mysql in 'init_by_lua'.

Thanks

Neither lua-resty-memcached nor lua-resty-mysql are usable in the
init_by_lua* context because the cosocket API is currently disabled
and not supported in that context.

I understand your use case and this has been a TODO item. You're
welcome to contribute a patch to speed things up :)

Hi agentzh-san,

Thank you for your reply.

I understand that reason and the situation.

Thank you for the catch-up to TODO.

I love ngx_lua seriously.
