Thread pool in C++ not using references from args

I am trying to get a thread pool to run a method were the arguments are passed by reference. The method I want to run is:

void Foo(const std::vector &arg1, std::vector &arg2, int size) {//modify elements of arg2}

I am submitting this function to a thread pool:

According to std::bind documentation:

The return type of std::bind holds a member object of type std::decay::type constructed from std::forward(f), and one object per each of args..., of type std::decay::type, similarly constructed from std::forward(arg_i).

Thanks to decay, the arguments are "stored-by-value", which means the arguments are either copy-constructed or move-constructed. This explains their different address.

As usually in such situations, the solution is in using std::reference_wrapper:

QUESTION

Optimising MySQL LEFT JOIN query for simple three table schema?

Asked 2019-Jan-21 at 17:21

I've written a job request system in PHP with a MySQL database and I'm having an issue with a slow query.

My schema (simplified) is as follows:

tbl_job
job_id
job_desc requester_user_id

tbl_user
user_id
user_name

tbl_workermap
workermap_id
job_id
worker_user_id

A table containing the jobs, a user table for the possible workers and one to map workers to jobs. A job can have one or more workers, a worker can have one or more jobs.

tbl_user contains both users who request work, and those that work on the jobs, so user IDs are stored under worker_user_id in tbl_workermap and requester_user_id in tbl_job

When a job is logged it creates an entry in tbl_job but nothing in tbl_workermap until someone specifically assigns a worker. This means that when I query the jobs I do it with a left join as there are not entries in tbl_workermap for every job:

If you have not already, create a clustered index by setting a primary key (assuming the tables are properly normalized). (If you haven't, you will likely want to setup foreign key constraints as well.)

If this question were involved Microsoft SQL Server, I would recommend creating a stored procedure, especially if this is a query run frequently as some sort of regular process. As noted in this answer, however, primary performance benefit for simple queries like this will be from table design and indices.

Why the job stored in DB when loaded runs for ever?

Asked 2017-Nov-20 at 05:35

I'm trying to add the Jobs to DB and then load them when the script runs again. The following code adds it to db but when you restart the script it loads the job but runs it for ever. It seems that the job import is correct but I can not figure out why it is running Wilde?

Here is the solution I have found. We need to convert the loaded time from the DB into date time object cause it is stored as TEXT.

In the code I entered for the question I needed to add .time() to make the conversion complete.
